Novel Alkoxide Cluster Topologies Featuring Rare Seesaw Geometry at Transition Metal Centers

Abstract

Caution! Chemists playing: Novel clusters of the form [M2Li2Cl2(OR)4] featuring rare seesaw geometry at the transition metal centers were synthesized for M=Cr-Co. The use of sterically hindering alkoxide ligands, as well as the inclusion of lithium ions in the structures enforces this highly unusual configuration.
