A mixed-metal pentanuclear complex containing linked Ni(II)N2S2 and Cu(I)I units

Bis[(1S,2S)-trans-3,3'-(1,2-cyclohexanediyldinitrilo)bis(2-methylpropane-2-thiolato)]-1 kappa(4)N(1),N-1',S-1,S-1';2 kappa(4)N(2),N-2',S-2,S-2';3 kappa(2)S(1),S-2';4 kappa(2)S(1'),S-2;5 kappa(2)S(1'),S-2'-tribis(acetonitrile solvate, [{Ni(C14H28N2S2)}(2)(CuI)(3)].2CH(3)CN, is ne of a number of possible novel pentanuclear complexes formed from M(II)N(2)S(2) units with available donating thiolate ligands. In the title conmpound, three (CuI)-I-I groups bridge thiolate ligands from two approximately square-planar [(NiN)-N-II(amine)(2)S(thiolate)(2)] units to form the pentanuclear complex. The coordination geometry of each Cu atom is approximately trigonal planar.
