[Ni₅S(SBu^t)₅]^–and [Ni₃S(SBu^t)₃(CN)₃]^2–, novel complexes with sulfur-capped, thiolate-bridged polygonal metal frames

Abstract

[Ni5S(SBut)5]–, an unprecedented pentanuclear sulfide thiolate cluster anion of fivefold symmetry containing a regularly shaped pentagonal nickel frame capped by a µ5 sulfide ion, and [Ni3S(SBut)3(CN)3]2–, a related complex of threefold symmetry with additional cyanide ligands, are described.
