metal-organic compounds
In the title compound, [Fe(C12H8N2)3](C4O4)·8H2O or [Fe(phen)3]sq·8H2O, where phen is 1,10-phenanthroline and sq is the squarate dianion (C4O4)2−, the FeII centre has a distorted octahedral coordination geometry comprising six N atoms from the three bidentate chelating phen ligands. An extensive three-dimensional network of Owater—HO, Owater—HOwater and C—HO hydrogen-bonding interactions is responsible for crystal stabilization.
