A MIXED-METAL PENTANUCLEAR COMPLEX CONTAINING LINKED NI(II)N2S2 AND CU(I)I UNITS

nediyldinitrilo)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(C14H28N2 S2)}(2)(CuI)(3)].2CH(3)CN, is ne of a number of possible novel pentanu clear complexes formed from M(II)N(2)S(2) units with available donatin g thiolate ligands. In the title conmpound, three (CuI)-I-I groups bri dge thiolate ligands from two approximately square-planar [(NiN)-N-II( amine)(2)S(thiolate)(2)] units to form the pentanuclear complex. The c oordination geometry of each Cu atom is approximately trigonal planar.
