Synthesis and X-Ray Crystal Structure of Bis(tetrahydroborato)-bisdicobalt(I), Co2(BH4)2(Ph2P5PPh2)2*0.5C6H6: a Novel Mode of Tetrahydroborate Co-ordination

Article abstract of DOI:10.1039/c39830001308

The title compound, obtained as one of several intermediates in a complex sequence of reactions involving Co^II, NaBH4, and α,ω-bis(diphenylphosphino)alkanes, is isolated as a phosphine-bridged binuclear species in which each of two tetrahydroborato groups also bridges the two Co^I units via the previously unknown M-H-BH2-H-M type of linkage; an additional and unexpected feature of the X-ray crystal structure is that one hydrogen atom of each of the two central BH2 groups also acts as a bridging ligand.
