The crystal structure of the title compound, [MnCl(C(28)H(22)N(2)O(2))(C(2)H(6)O)], has been determined at 173 (2) K in the non-centrosymmetric space group P2(1)2(1)2(1). The asymmetric unit contains two molecular units. An intermolecular O-H.Cl hydrogen bond is formed between the OH group of an ethanol molecule coordinated to the Mn atom and the coordinated Cl(-) anion, and so polymeric chains of Mn-containing fragments are formed [O-H.Cl = 3.1281 (16) and 3.1282 (15) A]. The Mn atoms have a pseudo-octahedral coordination sphere, with the four donor atoms of the Schiff base forming an equatorial plane [Mn-O distances are 1.8740 (13), 1.8717 (13), 1.8749 (13) and 1.8823 (13) A, and Mn-N distances are 1.9868 (15), 1.9910 (14), 1.9828 (15) and 1.9979 (14) A]. The axial positions are occupied by an ethanol molecule [Mn-O distances of 2.3069 (15) and 2.3130 (15) A] and a Cl(-) ligand [Mn-Cl distances of 2.5732 (6) and 2.5509 (6) A].
标题化合物[MnCl(C₂₈H₂₂N₂O₂)(C₂H₆O)]的晶体结构已在173(2)K下于非中心对称空间群P2₁2₁2₁中测定。不对称单元包含两个分子单元。与锰原子配位的乙醇分子的羟基与配位的Cl⁻阴离子之间形成分子间O-H…Cl氢键，从而形成含锰片段的聚合物链[O-H…Cl = 3.1281(16)和3.1282(15) Å]。锰原子具有一个伪八面体配位球，席夫碱的四个供体原子形成一个赤道平面[Mn-O距离为1.8740(13)、1.8717(13)、1.8749(13)和1.8823(13) Å，Mn-N距离为1.9868(15)、1.9910(14)、1.9828(15)和1.9979(14) Å]。轴向位置由一个乙醇分子[Mn-O距离为2.3069(15)和2.3130(15) Å]和一个Cl⁻配体[Mn-Cl距离为2.5732(6)和2.5509(6) Å]占据。
