Tris(1,10-phenanthroline-kappa(2) N,N '')iron(II) squarate octahydrate

Abstract

In the title compound, [Fe(C12H8N2)(3)](C4O4)center dot 8H(2)O or [Fe(phen)(3)]sq center dot 8H(2)O, where phen is 1,10-phenanthroline and sq is the squarate dianion (C4O4)(2-), the Fe-II centre has a distorted octahedral coordination geometry comprising six N atoms from the three bidentate chelating phen ligands. An extensive three-dimensional network of O-water - H center dot center dot center dot O, O-water - H center dot center dot center dot O-water and C - H center dot center dot center dot O hydrogen-bonding interactions is responsible for crystal stabilization.
