Crystal and molecular structure and magnetic properties of catena-µ-acetato-[NN′-ethylenebis(salicylaldiminato)]manganese(III). A linear-chain complex containing a single anti-anti acetate bridge

Abstract

The crystal and molecular structure of the title compound have been determined by single-crystal X-ray analysis All non-hydrogen atoms conform to space group P2/c with a= 6·536 ± 0·007, b= 7·768 ± 0·008, c= 17·194 ± 0·017 Å, β= 108·8 ± 0·1°. Z= 2. The structure has been determined from diffractometer data by Patterson and Fourier methods and refined to R 0·073 for 1211 observed reflections. The structure consists of linear polymeric chains of Mn(salen) moieties bridged by single acetate groups in an anti-anti configuration. The available magnetic data is shown to be consistent with this model.
