Crystal structure of bis(1,3-bis{[(1H-pyrrol-2-yl)methylidene]amino-κN}propan-2-olato-κO)manganese(III) nitrate methanol monosolvate

Abstract

The asymmetric unit of the title compound, [Mn(C13H15N4O)2]NO3·CH3OH, contains two independent complex cations, in each of which the MnIIIion is located on an inversion centre. The MnIIIion is coordinated by four N and two O atoms from two 1,3-bis{[(1H-pyrrol-2-yl)methylidene]amino}propan-2-olate ligands, resulting in a distorted octahedral geometry. The average Mn—ligand bond lengths in the two complex molecules are 2.074 and 2.079 Å. In the crystal, intermolecular N—H...O hydrogen bonds between the pyrrole group of the ligand and the non-coordinating nitrate ion give rise to a chain structure along [10-1]. The methanol solvent molecule and the nitrate ion are connected by an O—H...O hydrogen bond.
