摘要:
Reaction of Ni(CO)(4) with HN(SPPh2)(2) in tetrahydrofuran yielded the nickel(II) neutral complex [Ni-{(SPPh2)(2)}(2)N-S,S'].2THF. X-ray crystallography shows a square planar NiS4 core, with a center of inversion at Ni atom. It crystallized in the space group P(1)over-bar. This compound easily isomerizes in organic solvents at room temperature or by heating a solid-state sample to form the corresponding tetrahedral isomer.
