In the title compound, [Fe(CH(3)CN)(2)(C(14)H(32)O(4)P(2))(2)]Cl(2), the Fe(II) atom lies on a crystallographic inversion center and has a distorted trans-FeN(2)P(4) octa-hedral coordination environment arising from two P,P'-bidentate 1,2-bis-[bis-(3-hydroxy-prop-yl)phosphino]ethane ligands in the equatorial plane and two acetonitrile mol-ecules in the axial positions. One of the pendant -(CH(2))(3)OH groups of the ligand is disordered over two sets of sites in a 0.597 (5):0.403 (5) ratio. In the crystal, O-H⋯Cl and O-H⋯O hydrogen bonding helps to establish the packing.
在标题化合物[Fe(CH₃CN)₂(C₁₄H₃₂O₄P₂)₂]Cl₂中，Fe(II)原子位于一个晶体学反演中心，具有扭曲的反式-FeN₂P₄八面体配位环境，赤道平面上有两个P,P'-双齿的1,2-双-[双-(3-羟基丙基)膦基]乙烷配体，轴向位置有两个乙腈分子。配体的一个悬垂-(CH₂)₃OH基团在两组位置上无序排列，比例为0.597(5):0.403(5)。在晶体中，O-H⋯Cl和O-H⋯O氢键有助于形成堆积。
