Abstract: In the title compound, [Fe(CH₃CN)₂(C₁₄H₃₂O₄P₂)₂]Cl₂, the Fe^II atom lies on a crystallographic inversion center and has a distorted trans-FeN₂P₄ octahedral coordination environment arising from two P,P'-bidentate 1,2-bis[bis(3-hydroxypropyl)phosphino]ethane ligands in the equatorial plane and two acetonitrile molecules in the axial positions. One of the pendant -(CH₂)₃OH groups of the ligand is disordered over two sets of sites in a 0.597 (5):0.403 (5) ratio. In the crystal, O-HCl and O-HO hydrogen bonding helps to establish the packing.
