High‐Spin Square‐Planar Co^II and Fe^II Complexes and Reasons for Their Electronic Structure

Abstract

It's hip to be square: Two high-spin, square-planar {MO4} complexes are prepared, including the first molecular example with M=CoII (see structure). Structural, spectroscopic, and magnetic susceptibility characterization allows a description of the ligand features required for this highly unusual electronic structure.
