title: Exchange-coupled oxygen- and sulfur-bridged cyclopentadienyl-manganese(II) cages.
abstract: The trimetallic complex [{CpMn(μ-OSiPh3)2}2Mn] (1) and the heterocubane [CpMn(μ3-SSiPh3)]4 (2) are formed by deprotonation of Ph3SiQH (Q = O, S) by manganocene, or by transmetallation of manganocene by Ph3SiQLi. The Mn(II) centres in 1 and 2 are antiferromagnetically coupled, with J = −4.4 and −3.0 cm(−1) in 1 and 2, respectively (−2J formalism).
