Abstract

The trimetallic complex [{CpMn(μ-OSiPh(3))(2)}(2)Mn] () and the heterocubane [CpMn(μ(3)-SSiPh(3))](4) () are formed by deprotonation of Ph(3)SiQH (Q = O, S) by manganocene, or by transmetallation of manganocene by Ph(3)SiQLi. The Mn(ii) centres in and are antiferromagnetically coupled, with J = -4.4 and -3.0 cm(-1) in and , respectively (-2J formalism).
