Docetaxel: Solid state characterization by X-ray powder diffraction
and
thermogravimetry
JOURNAL DE PHYSIQUE IV, 11, 2001, 221-226.
Docetaxel, a stoichiometric hydrate containing three water molecules
per molecule of drug substance, is thermodynamically stable
under
ambient conditions of pressure, temperature and relative
humidity.
Dehydration of this form was subjected to X-ray powder
diffraction
(XRPD) and thermogravimetric experiments. To obtain a
better
understanding of the observed structural changes between
trihydrate and
dehydrated forms, the crystalline structure of docetaxel
was refined
using high resolution XRPD data coupled with an ab initio
direct space
method.

Synthesis, structure, and properties of a three-dimensional
open-framework niobium fluorogermanate (NGH-5)
CHEMISTRY OF MATERIALS 13, 2001, 4676-4680.
The low-temperature hydrothermal. synthesis and crystal structure
of a
new open-framework niobium germanate phase is reported.
(C6H18N2).
Ge2.2Nb0.8O6.8F1.2 (NGH-5) was synthesized from GeO2,
Nb2O5, and HF
(aq) by using 1,4-trans-diaminocyclohexane (1,4-DACH)
as an organic
structure directing agent. The structure of NGH-5 was
determined ab
initio by using powder X-ray diffraction techniques and
consists of a
negatively charged three-dimensional Nb/Ge/O/F framework
containing
three orthogonal channel systems. Two of the channels
are delimited by
10-membered rings of NbO5F octahedra and GeO4 tetrahedra;
the third is
delimited by an 8-membered ring. Charge-balancing (C6H18N2)(2+)
cations
are encapsulated within the framework and are located
at the center of
the 10-membered ring channels. The NGH-5 framework is
characterized by
a low framework density and is closely related to the
recently reported
zirconium germanate ASU-15.

diffraction data and refined by the Rietveld method (RF

to sulfate
oxygen atoms according to a monodentate-bidentate mode.
Through
bridging sulfate groups, the LaO9 polyhedra are joined
into an anionic
layer-like structure parallel to (010). To stabilise the
structure the
NH4+ cations lying between the layers form short contacts
with the
terminal O atoms in the sulfate groups, The thermal behaviour
of beta
-La(NH4)(SO4)(2) and alpha -LaK(SO4)(2), investigated
by
thermodiffractometry, is also described. The ammonium
beta phase
decomposes into the oxysulfate La2O2SO4 through the departure
of
ammonium sulfate in the first stage. According to a similar
thermal
treatment, the potassium a phase transforms into a polymorph
(beta) and
the phase transition process is reversible upon cooling,
The
diffraction patterns of these new varieties of LaK(SO4)(2)
have been
indexed.

A new compound CaGaBO4 was synthesized by solid state reaction at high

from X-ray
powder diffraction data. The refinement was carried out
using the
Rietveld method, and the final refinement converged with
R-p=10.2% and
R-wp=14.5%. It crystallizes in the orthorhombic system
with the space
group Ccc2 and lattice parameters a=15.473(1) Angstrom,

Angstrom, c=5.8392(6) Angstrom, and Z=8. The crystal structure
of
CaGaBO4 is formed by BO3-triangle groups, GaO4-tetrahedron
groups that
are linked to chains along the c-axis, and six-coordinated
calcium
groups, in which there is a channel of similar to5 Angstrom

along the c-axis. The XRD results show that no phase transition
occurs
between -173 and 227 degreesC. The lattice parameters

Phase equilibria in the palladium-rich part of the gallium-palladium
system. The crystal structures of Ga3Pd7 and Ga1-xPd2+x
JOURNAL OF ALLOYS AND COMPOUNDS 316, 2001, 99-106.
The phase relations between the palladium-rich phases of the
gallium-palladium system are clarified by combining preparative
methodologies with powder X-ray diffraction and thermochemical
analyses. A modified phase diagram of the palladium-rich
part of the
system is presented. The structure of Ga3Pd7, decomposing
peritectoidally at 881(2)degreesC, was determined by powder
X-ray
diffraction and refined by a Rietveld profile fit. Ga3Pd7
adopts a new
structure type with monoclinic space group symmetry: C2/m,
Z = 2, a =
1359.46(2) pm, b=405.510(5) pm, c=544.339(6) pm, beta
=105.2219(7)degrees, wR(p) = 0.082. The structure can
be seen as a
strongly distorted, ordered variant of a respective GaxPd1-x
fcc solid
solution. It comprises two structural motifs: layers of
columns of
fused (GaPd6/2)(2) prisms are formally separated by equiatomic
GaPd
layers. The impact of the composition on the structure
of Co2Si-type
Ga1-xPd2+x was studied. There exists a symmetry relation
between the
cubic close-packed arrangement of atoms and the structures
of the
Co2Si-type branch of AB(2) phases with Pearson symbol
oP12 and space
group symmetry Pnma.

The fine structure of YCuO2+x delafossite determined by synchrotron
powder diffraction and electron microscopy
JOURNAL OF SOLID STATE CHEMISTRY 156, 2001, 428-436.
YCuO2 delafossite crystallizes into two stacking variants; hexagonal
2H
or rhombohedral 3R, depending on the preparation conditions.
The
structure of the fully oxygenated material YCuO2.50 has
been determined
as orthorhombic (a(O) = 6.1961 Angstrom; b(O) = 11.2158
Angstrom; c(O)
= 7.1505 Angstrom; space group Pnma). The structure is
based on the
hexagonal 2H structure (a(O) = a(H)root3; b(O) = c(H);
c(O) = 2a(H)).
Upon incomplete oxidation, a different YCuOZ phase with
ideal
composition YCuO2.33 and lattice parameters a(H root)3,
a(H)root3, c(H)
is also formed. Diffraction patterns are often very complex
because of
the presence of planar defects and intergrowth of both
phases. Under
electron beam irradiation, oxygen is released from the
structure and
one phase gradually transforms into the other.

NaZn(H2O)(2)[BP2O8] . H2O: A novel open-framework borophosphate
and its reversible dehydration to microporous sodium zincoborophosphate
Na[ZnBP2O8] . H2O with CZP topology
CHEMISTRY-A EUROPEAN JOURNAL 7, 2001, 834-839.
Crystals of NaZn(H2O)(2)[BP2O8]. H2O were grown under mild hydrothermal
conditions at 170 degrees C. The crystal structure (solved
by X-ray
single-crystal methods: hexagonal. P6(1)22 (no. 178).
a = 946.2(2). c =
158.3.5(1) pm. V = 1227.8(4) 10(6) pm(3). Z = 6) exhibits
a chiral
octahedral-tetrahedral framework related to the CZP topology
and
contains helical ribbons of corner-linked berate and phosphate
tetrahedra. Investigation of the thermal behavior up to
180 degrees C
shows a (reversible) dehydration process: this leads to
the microporous
compound Na[ZnBP2O8].H2O. which has the CZP topology.
The crystal
structure of Na[ZnBP2O8].H2O was determined by X-ray powder
diffraction
by using a combination of simulated annealing, lattice-energy
minization, and Rietveld refinement procedures (hexagonal,
P6(1)22 (no.

dehydration
concerns the coordination of Zn3+ changing from octahedral
to
tetrahedral arrangement.

JOURNAL OF PHYSICS AND CHEMISTRY OF SOLIDS, 62, 2001, 1393-1399.
omega -VOPO4 has been prepared by thermal decomposition of different
oxovanadium hydrogen phosphates, namely VO(HPO4) nH(2)O
(n = 2(alpha),
2(beta) and 4) and beta -NH4(VO2)(HPO4). The omega -VOPO4
phase only
remains well crystallised at relatively high temperatures.
Its crystal
structure has been determined ab initio from X-ray powder
diffraction
data collected at 4750C. The cell is tetragonal (space
group P4(2)/mmc)
with a = 4.8552(3) Angstrom and c = 8.4301(6) Angstrom.
Starting
positional parameters were obtained by direct methods,
and the
structure was refined using Rietveld profile refinement

Disorder of two oxygen sublattices is observed. To rationalise
