New high-nuclearity Ni-Pt carbonyl clusters: synthesis and X-ray structure of the ordered [Ni24Pt14(CO)44]4- and the substitutionally Ni/Pt disordered [Ni10(Ni6-xPtx)Pt8(CO)30]4- (x = 1.92) tetraanions.

Abstract

The reaction of [NnBu4]2[Ni6(CO)12] in THF solution with 1.5-2 equivalents of K2PtCl4 leads to formation of the [Ni24Pt14(CO)44]4- and [Ni10(Ni6-xPtx)Pt8(CO)30]4- (x approximately 2) tetraanions, the latter presents a localised substitutional Ni/Pt disorder and an unprecedented close-packed metal structure.
