摘要：

The N2S2 ligand N,N″-dimethyl-N,N′-bis(β-mercaptoethyl)ethylenediamine, H2L, reacts with NiCl2•6H2O in methanol solution to yield a trinuclear species of stoichiometry [Ni3L2]Cl2•2H,O. This compound crystallizes in the monoclinic space group P21/n with a = 19.917 (7) Å, b = 5.453 (3) Å, c = 13.508 (6) Å, β = 100.81 (4)°, and Z = 2. The trinuclear unit consists of two pseudosquare-planar terminal NiN2S2 environments arranged in a chair conformation about a central NiS4 plane, with the central nickel occupying a crystallographic inversion center. A dihedral angle of 107.84 (7)° exists between nickel planes unrelated by symmetry. Ni–N distances are 1.938 (4) and 1.951 (3) Å, Ni-S distances in the NiN2S2 environment are 2.144 (1) and 2.160. © 1990, American Chemical Society. All rights reserved.
