The asymmetric unit of the title Schiff base complex, [Mn(C(36)H(46)N(2)O(2))Cl], comprises two crystallographically independent mol-ecules. The Mn(III) centre in each mol-ecule adopts a distorted square-pyramidal geometry. Each Mn(III) ion is coordinated by the N(2)O(2) atoms of the tetra-dentate Schiff base ligand forming the basal plane and the coordinated chloride anion occupies the apical position. Four bifurcated intra-molecular C-H⋯O contacts stabilize the mol-ecular structure. In the crystal packing, mol-ecules are linked into dimers via inter-molecular C-H⋯Cl contacts and further stabilized by C-H⋯π inter-actions. The crystal studied was a non-merohedral twin, the refined ratio of the twin components being 0.441 (1):0.559 (1).
标题席夫碱配合物[Mn(C₃₆H₄₆N₂O₂)Cl]的不对称单元包含两个晶体学独立的分子。每个分子中的Mn(III)中心采用扭曲的四方锥几何构型。每个Mn(III)离子由四齿席夫碱配体的N₂O₂原子配位形成基面，配位的氯离子占据顶端位置。四个分叉的分子内C—H⋯O接触稳定了分子结构。在晶体堆积中，分子通过分子间C—H⋯Cl接触连接成二聚体，并通过C—H⋯π相互作用进一步稳定。所研究的晶体为非等轴孪晶，孪晶组分的精修比例为0.441 (1):0.559 (1)。
