Abstract
Reaction of RECl2 (R- = C(SiMe3)(2)(6-Me-2-pyridyl)(-), E = P or As) with L iAlH4 in THF affords directly bonded aluminium hydride-pnictide hydride com plexes as weakly associated hydride bridged dimers, [RE(H)-Al(H)(2)](2); a strong solvent dependency of these reactions, which had previously been obs erved with the formation of the disecondary diphosphane in Et2O (E = P), is further confirmed by the formation of RAsH2 from RAsCl2 and LiAlH4 in Et2O .
