Synthesis and molecular structures of nido-[9-(η-C5H5)-7,8,9-C2NiB8H11], nido-[9-(η-C5H5)-µ10,11-(Ph3PAu)-7,8,9-C2NiB8H10], and closo-[1,3-(η-C5H5)2-1,2,3,4-CrCCrCB8H10]; evidence for a multiple metal–metal bond in a dimetallacarbaborane
Abstract
From nido-5,6-C2B8H12, the compounds nido-[9-(η-C5H5)-7,8,9-C2NiB8H11], nido-[9-(η-C5H5)-µ10, 11-(Ph3PAu)-7,8,9-C2NiB8H10], and closo-[1,3-(η-C5H5)2-1,2,3,4-CrCCrCB8H10] have been synthesised, and their structure identities established by X-ray crystallography.
