An enneanuclear nickel sulphide with a confacial bi-octahedral geometry. X-Ray crystal structure of [Ni9(µ4-S)3(µ3-S)6(PEt3)6][BPh4]2
Abstract
An X-ray analysis of [Ni9S9(PEt3)6][BPh4]2 shows that the nine nickel atoms in the [Ni9S9(PEt3)6]2+ cluster lie in a confacial bi-octahedral arrangement and are held together by bridging sulphur atoms, while six phosphine groups complete the co-ordination around the nickel atoms.
