Title

Magnetic Studies of a Linear Chromium (III) Trimer of a Triketone

Abstract

The trinuclear chromium(III) triketonate complex, Cr3(lig)2, where lig = 1,5-diphenyl-1,3,5-pentanetrionato, has been synthesized and characterized by magnetic susceptibility, ESR, and electronic spectra. The complex has g = 1.977 and exhibits antiferromagnetic interactions. The magnetic interaction fits an isosceles arrangement of the coupling constants, with J = -6.00 cm-1 between two pairs of adjacent metal atoms and J′ = -1.35 cm-1 between the third metal pair. This arrangement is compatible with the essentially linear configuration of the metal atoms also expected with the planar ligands. © 1986 American Chemical Society.
