A new series of four-coordinate bis chelate complexes of the general type [MS4C4(CF3)4]z has been prepared. This series is closely related to that previously described1,2 containing [MS4C4(CN)4]2 complexes (z = -1, -2) in that its members undergo facile one-electron transfer reactions and those with z = -1, -2 are believed to have a planar structure. Complexes with z = -2, M = Pd, Pt, Co; z = -1, M = Pd, Pt, Co, Fe; and z = 0, M = Pt, Co, have been synthesized and supplement the nickel complexes with z = 0, -1, -2 obtained in earlier work.1,2 The syntheses of all complexes are presented in detail. Chemical stabilities are discussed in terms of polarographic half-wave potentials. The results of magnetic susceptibility, electron spin resonance, nuclear magnetic resonance, and infrared spectral studies are presented and discussed in terms of probable electronic structures and chemical bonding in the complexes.
