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.
标题化合物[Mn(C₁₃H₁₅N₄O)₂]NO₃·CH₃OH的不对称单元包含两个独立的络合阳离子，每个阳离子中的Mn(III)离子位于一个对称中心上。Mn(III)离子由来自两个1,3-双-{[(1H-吡咯-2-基)亚甲基]氨基}-丙-2-醇配体的四个N原子和两个O原子配位，形成扭曲的八面体几何构型。两个络合分子中Mn-配体的平均键长分别为2.074 Å和2.079 Å。在晶体中，配体的吡咯基团与非配位硝酸根离子之间的分子间N-H⋯O氢键形成了沿[10-1]方向的链状结构。甲醇溶剂分子与硝酸根离子通过O-H⋯O氢键相连。
