THE SYNTHESIS AND SOLID-STATE PROPERTIES OF THE SALTS OF [M(S2C2(CN)2)2]2- (WHERE M = NI, PD OR PT) WITH SMALL-GROUP I AND GROUP II CATIONS, INCLUDING THE CRYSTAL-STRUCTURE OF RB2[NI(S2C2(CN)2)].H2O

The synthesis and characterization of the salts of [M(S2C2(CN)2)2]2- (where M = Ni, Pd and Pt) with small counter cations is described. The solid-state electronic spectra of the salts indicate some degree of interaction which is cation dependent. The crystal structure of Rb2[Ni(S2C2(CN)2)2]· H2O shows the anions to be well separated with no S...AlS contacts of less than 4 Å. © 1990.
