Abstract
The title compound, obtained as one of several intermediates in a complex sequence of reactions involving CoII, 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 CoI 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.Keywords
