Description

Spectral (IR, Raman) and X-ray structural investigations of CdBr2xMB (MB-2,4,6,8-tetramethyl-2,4,6,8-tetraazabicyclo(3.3.0)-octadione-3.7 m, mebicar) (λMo, 634 reflections, R=0.045) are performed. Rhombic crystals: a=3.9921(7), b=10.6938(25), c=14.9947(62)A,L=2, sp. gr. Fnmm. The structure is polymerically laminated. Mebicar molecules play the role of bidentate-bridge ligands. O atoms of both carbonyl groups bind Cd atoms of the neighbouring complexes in chains directed along y axis. In the direction of x axis such chains are connected by bridge Br atoms in layers parallel to (xy0) plane. the coordination polyhedron of Cd atoms is a distorted octahedron. Bond lengths Cd-Br 2.738, Cd-O 2.37 A Bond lengths Cd-Br 2.738, Cd-O 2.37 A
