Abstract

The synthesis and characterisation of the homoleptic transition-metal complexes (1,8-Ph2-3,6-Me2C12H4N)2M (M = Cr, 1; M = Mn, 2; M = Fe, 3; M = Co, 4) are described. Formally two-coordinate, the solid-state structures of 2 and 3 reveal near-linear N–M–N geometries and significant bending of the flanking phenyl groups towards the metal centres. Solid-state magnetic measurements reveal high spin metal centres in 1–4; computational calculations for the model complexes M(1,8-Ph2C12H6N)2 (M = Cr–Co) confirm the presence of high-spin configurations within these bis-carbazolido compounds and an orbital ordering of δ < π < σ for these systems.(© Wiley-VCH Verlag GmbH & Co.
