N2 - Highly hygroscopic, black, prism-like crystals separated out from CH3CN solutions containing (Et4N)2NiCl4 and 3-dimethylamino-1-propanethiol at several mole ratios. Crystals of [Ni6{S(CH2)3N(CH3)2}12] are orthorhombic, space group P21212 with a = 30.197(6), b = 29.231(4), c = 10.649(1) Å and Z = 4. The Ni6S12 core of each molecular unit constitutes a hexagonal prism whose rectangular faces are NiS4 coordination planes (NiS = 2.19 Å; SNiS = 82.2°, 98.05°). Approximate diameters for the Ni6 and S6 rings are 5.85 and 6.60 Å, respectively. The allowed molecular symmetry for the Ni6S12 core, D6h, is reduced to D3d when the axial and equatorial SC bonds are included. © 1989.
