A direct access to heterobimetallic complexes by roll-over cyclometallation†
Abstract
Complexes of the type [Cp*Ir(N,N′)Cl]+ (N,N′ = 2-(2-dialkylaminopyrimidin-4-yl)pyrimidine) can undergo roll-over cyclometallation leading to a novel N,N′-donor site. Following this strategy heterobimetallic complexes including iridium(III) and a Group X metal centre in the oxidation state +II were achieved.
