The trinuclear cationic zinc hydride cluster [(IMes) 3 Zn 3 H 4 (THF)](BPh 4 ) 2 ( 1 ) was obtained either by protonation of the neutral zinc dihydride [(IMes)ZnH 2 ] 2 with a Brønsted acid or by addition of the putative zinc dication [(IMes)Zn(THF)] 2+ . A triply bridged thiophenolato complex 2 was formed upon oxidation of 1 with PhSSPh. Protonolysis of 1 by methanol or water gave the corresponding trinuclear dicationic derivatives. At ambient temperature, 1 catalyzed the hydrosilylation of aldehydes, ketones, and nitriles. Carbon dioxide was also hydrosilylated under forcing conditions when using (EtO) 3 SiH, giving silylformate as the main product.
