Aquachloro[N,N'-ethylenebis(salicylideneiminato)]manganese(III)

Abstract

The title compound, aquachloro(2,2'-[1,2-ethanediylbis(nitrilomethylidyne)]diphenolato-kappa4O,N,N',O')manganese(III),[MnCl(C(16)H(14)N(2)O(2))(H(2)O)], is a neutral manganese(III) complex with a pseudo-octahedral metal centre. The equatorial plane comprises the four donor atoms of the tetradentate Schiff base ligand [Mn-O 1.886 (4) and 1.893 (4) A, and Mn-N 1.978 (5) and 1.982 (5) A], with a water molecule [Mn-O 2.383 (4) A] and a Cl- ligand [Mn-Cl 2.4680 (16) A] completing the coordination sphere. The distorted geometry is highlighted by the marked displacement of the Mn(III) ion out of the least-squares plane of the four Schiff base donor atoms by 0.165 (2) A. These monomeric Mn(III) centres are then linked into a polymeric array via hydrogen bonds between the coordinated water molecule and the phenolic O-atom donors of an adjacent Mn(III) centre [O-H.O 2.789 (5) and 2.881 (5) A].
