TRI-MU-CHLORO-BIS(1,4,7-TRITHIACYCLONONANE)DINICKEL(II) TETRAFLUOROBORATE ACETONITRILE SOLVATE

[Ni2(C6Hl2S3)2Cl3][BF4].C2H3N, M(r) = 712.28, monoclinic, P2(1)/c, a = 12.379 (5), b = 13.790 (6), c = 16.031 (6) angstrom, beta = 99.73 (4)-degrees, V = 2697 angstrom3, Z = 4, D(x) = 1.754 Mg m-3, lambda(Mo Kalpha) = 0.71073 angstrom, mu = 2.184 mm-1, F(000) = 1448, T = 150.0 (1) K, R = 0.0562 for 2173 unique observed reflections. Each Ni atom is approximately octahedrally coordinated to all three S atoms of one ligand molecule and to the three Cl atoms. Unusually, the Ni(II) centres are triply chloride bridged, giving a cation which consists of two face-sharing octahedra in which the Ni...Ni distance is 2.9211 (20) angstrom.
