title: Crystal structure of bis-(1,3-bis-{[(1H-pyrrol-2-yl)methyl-idene]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 Mn(III) ion is located on an inversion centre. The Mn(III) ion is coordinated by four N and two O atoms from two 1,3-bis-{[(1H-pyrrol-2-yl)methyl-idene]amino}-propan-2-olate ligands, resulting in a distorted octa-hedral geometry. The average Mn-ligand bond lengths in the two complex mol-ecules are 2.074 and 2.079 Å. In the crystal, inter-molecular 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 mol-ecule and the nitrate ion are connected by an O-H⋯O hydrogen bond.
