In these final examples, Otero and coworkers described the reaction of a niobocene hydride (134) with triphenylgermanium hydride to afford niobocene germyl complexes... 

In contrast to the alkyl, silyl, and germyl complexes, when E is Sn, not SnR3 but only one alkyl group on the Sn migrates to the phosphenium P to give a stannylene complex (39).23,34 Since the transition metal-phosphorus bond has considerable double-bond character (see below), the conversion from 36 to 39 corresponds to a double-bond migration from Fe=P to Fe=Sn.

Phosphonium salts of anionic trihydridogermyl metal carbonyl complexes for V, Nb, Cr, Mo, W, Mn, Re, Co and Ni have been synthesized by substitution of carbonyl group with trihydrido germane, —GeH3 " (equation 9). Hydridogermyl metal complexes are the precursors for metal germylenes and polynuclear metal germyl complexes .
