Abstract

Three Re(v) N-heterocyclic carbene complexes [ReO(OH)(L(Me))(2)][PF(6)](1.4)[ReO(4)](0.6), [ReO(OH)(L(iPr))(2)][PF(6)](1.4)[ReO(4)](0.6) and [ReO(OH)(L(Bn))(2)][PF(6)](1.3)[ReO(4)](0.7) (L(Me) = 1,1'-methylene-bis(3-methylimidazole-2-ylidene); L(iPr) = 1,1'-methylene-bis(3-isopropylimidazole-2-ylidene) and L(Bn) = 1,1'-methylene-bis(3-benzylimidazole-2-ylidene)) with trans oxo and hydroxo at axial positions have been synthesized.
