trans-Bis(acetonitrile-κN)bis{1,2-bis[bis(3-hydroxypropyl)phosphino]ethane-κ2P,P′}iron(II) dichloride
Abstract
In the title compound, [Fe(CH3CN)2(C14H32O4P2)2]Cl2, the FeII 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—H...Cl and O—H...O hydrogen bonding helps to establish the packing.
