The title compound (WOS3Cu3 (gamma-pic)(6))Br(C36H42BrON6S3Cu3W, M-r = 1125
. 34) was synthesized and the structure was determined by X-ray diffraction
. The crystal belongs to the trigonal system with space group P(3)overbar.
The cell parameters are a = 12. 264(5), c = 15. 905(8) Angstrom , gamma = 1
20. 00 degrees, V = 2071(2)Angstrom (3), mu(MoK alpha) = 5. 490mm(-1), Z =
2, D-c = 1. 801g/cm(3), F(000) = 1104. Final R and Rw are 0. 052 and 0. 053
, respectively for 1901 (I greater than or equal to 2 sigma(I)) observed re
flections. The crystal molecule consists of (WOS3Cu3(gamma-pic)6)(+) anion
and Br-, where the anion is of a nest structure composed by one W atom, thr
ee Cu atoms and three mu(3)-S atoms. There is a C-3 axis across the W and S
atoms.
