metal-organic compounds
catena-Poly[[[dichloridoiron(II)]-μ-N,N′-bis(2-pyridylmethylene)benzene-1,4-diamine] methanol disolvate], [FeCl2(C18H14N4)]·2CH3OH, forms a one-dimensional coordination polymer. The polymeric chains run parallel to the c axis. O—HCl—Fe and C—HO hydrogen-bonding interactions with methanol solvent molecules stabilize the open supramolecular framework. Each FeII atom adopts an octahedral geometry coordinated by four N atoms from two N,N′-bis(2-pyridylmethylene)benzene-1,4-diamine ligands and completed by two cis Cl atoms. The compound has C2 (and Ci) molecular symmetry, which is coincident with the crystallographic twofold symmetry at (0, y, ). The one-dimensional structure is propagated via the crystallographic inversion center located at the benzene ring centroid (0, , 0).
