Sažetak
The triclinic structure of CrMogSeg ternary compound has been solved
on single crystals at RT. The triclinic unit-cell is: a = 6.738(2) A,
b = 6.710(2) A, c = 6.783(3) Å, a = 98.03(3)°,/? = 91.63(3)°, y = 94.65(3)°, V = 302.5 Å3, Z = 1, Dx = 6.913, space group PT, 1771 reflections, 71 refined parameters, R = 0.023.
The network framework is built up of distorted MogSeg cluster units. The originality of this structure is the new occupancy of chromium atoms. Chromium trivalent ions occupy a particular position just in the inversion centre in 1/2 0 0 and are surrounded by six selenium atoms forming a distorted octahedral site (site 2 of the channels). It corresponds to a translation of 1/2 a along the a rhombohedral axis of the Pb ions of the PbMogSeg structure corresponding to a change of symmetry R5 to PT.
