X-ray structure and variable temperature NMR spectra of [meso-triarylcorrolato]copper(III)

Inorg Chem. 2003 Jul 28;42(15):4495-7. doi: 10.1021/ic034080u.

Abstract

The diamagnetic square planar d(8) complexes [meso-arylcorrolato]copper(III) become paramagnetic upon warming, indicative of the equilibrium between the [corrolato]copper(III) and the [corrolato](+)* copper(II) forms of the complex. [meso-Triphenylcorrolato]copper(III) was structurally characterized and found to be saddled.
