Single crystals of the quasi-one-dimensional conductor (perylene)Co-bis(maleonitriledithiolate)(CH2Cl2)0.5 were prepared by electrocrystallization. The structure at room temperature is incommensurate with modulation wave vector (0.22a*, -0.13b*, -0.3

Synchrotron-radiation single-crystal x-ray diffraction is used to study the modulations corresponding to both the ${\mathbf{q}}^{1\mathrm{\ensuremath{-}}}$and ${\mathbf{q}}^{2}$-type charge-density waves (CDW's) in ${\mathrm{NbSe}}_{3}$. The ${\mathb

Neutron-diffraction experiments have been performed on a single crystal of {alpha}-U in the phase below 43 K, in which a charge-density wave (CDW) exists. We report on the identification of the superspace group in the CDW state. This is primitive mon

A procedure is presented for the automatic solution of composite (misfit) layer compounds, for the case when the composite crystal structure consists of two types of layer, each of which can be approximately described as a three-dimensional periodic

NbTe 4 presente une transition de phase du type lock-in vers 50 K. La microscopie electronique revele des discommensurations dont on etudie l'evolution thermique. On propose un modele de microstructure dans lequel le dephasage cooperatif entre segmen

The Patterson function for the Al6CuLi3 quasicrystal is calculated by Fourier transformation of the measured single-crystal x-ray-diffraction data. The resulting function exhibits peaks corresponding to interatomic distances which occur regularly in

Crystals containing stacks of TCNQ-ions have roughly thermal expansion coefficients along the stack, which are three times the values at right angles to it. It is shown that a simple degree of freedom argument, taking into account the librational mod

The application of superspace groups to short-period superstructures is considered. For niobium tri-sulfide this is worked out in detail. It is shown that in that case the superspace group provides more symmetry then given by the space group of the s
