Nb(η5-C5H4SiMe3)2(H)2(ER3), E = Si (12), Ge (2), Sn (11), were carried out. 12 reacts with H2 to give 1, but 2 and 11 were unreactive toward this reagent. Furthermore, a similar behavior was observed with CO and CN(2,6-Me2C6H3). Thus, 12 reacts with these reagents to give rise, after elimination of HSiPh3, to Nb(η5-C5H4SiMe3)2(H)(CO) and Nb(η5-C5H4SiMe3)2(H)(CN(2,6-Me2C6H3)), respectively, while 2 and 11 do
