In the asymmetric unit of the title compound, [Mn(C(2)O(4))(C(3)H(10)N(2))(2)]Cl·H(2)O, there are two independent Mn(III) complexes, two Cl(-) anions and two uncoordinated water mol-ecules. Each Mn(III) atom is hexa-coordinated by four N atoms from two propane-1,3-diamine ligands and two O atoms from one oxalate ligand, resulting in a slightly distorted octa-hedral MnO(2)N(4) geometry. Mn-O and Mn-N bond lengths are in the ranges 1.969 (2)-2.020 (3) and 2.068 (3)-2.113 (4) Å, respectively. There are weak inter-molecular O-H⋯O, O-H⋯Cl, N-H⋯O and N-H⋯Cl hydrogen bonds with D⋯A distances in the range 2.831 (4)-3.423 (3) Å.

在标题化合物[Mn(C₂O₄)(C₃H₁₀N₂)₂]Cl·H₂O的不对称单元中，有两个独立的Mn(III)配合物、两个Cl⁻阴离子和两个未配位的水分子。每个Mn(III)原子由来自两个1,3 - 丙二胺配体的四个N原子和来自一个草酸根配体的两个O原子六配位，形成略微扭曲的八面体MnO₂N₄几何构型。Mn - O和Mn - N键长分别在1.969 (2) - 2.020 (3) Å和2.068 (3) - 2.113 (4) Å范围内。存在弱的分子间O - H⋯O、O - H⋯Cl、N - H⋯O和N - H⋯Cl氢键，D⋯A距离在2.831 (4) - 3.423 (3) Å范围内。
