Abstract

In the title compound, [Ni3(C10H22N2S2)2](ClO4)2, the complex cation consists of a nickel(II) ion and two [Ni(C10H22N2S2)] units with an N2S2 tetra­dentate ligand, 3,3′-[1,2-ethane­diylbis(methyl­imino)]bis­(1-propane­thiol­ate). The central NiII ion is located on a crystallographic inversion centre and is bound to the four S atoms of the two [Ni(C10H22N2S2)] units to form a linear sulfur-bridged trimetallic moiety. The dihedral angle between the central NiS4 plane and the terminal NiN2S2 plane is 145.71 (5)°. In the [Ni(C10H22N2S2)] unit, the two methyl groups on the chelating N atoms are cis to each other, and the two six-membered N,S-chelate rings adopt a chair conformation. The Ni—S bond lengths and the S—Ni—S bite angles in the central NiS4 group are similar to those in the [Ni(C10H22N2S2)] unit.
