A cross-shaped Ag5Ti4 molecule based on a [Ag(CN)4]3− core
Abstract
K3[Ag(CN)4] (2) reacts with {[Ti](CCR)2}AgOClO3 {R = SiMe3, 1a; R = Ph, 1b; [Ti] = (η5-C5H4SiMe3)2 Ti} in a 1∶4 molar ratio to produce the nonametallic Ag5Ti4 species [Ag(CN→Ag{(RCC)2[Ti]})4 ](ClO4) (R = SiMe3, 3a; R = Ph, 3b) in which four heterobimetallic titanium(IV)–silver(I) tweezer units, [{[Ti](CCR)2}Ag]+, are bridged by a [Ag(CN)4]3− core; the reaction chemistry of 3 is reported.
