Tris(1,10-Phenanthroline-Kappa(2) N,N '')Iron(II) Squarate Octahydrate

Abstract

In the title compound, [Fe(C<inf>12</inf>H<inf>8</inf>N<inf>2</inf>) <inf>3</inf>](C<inf>4</inf>O<inf>4</inf>)·8H<inf>2</inf>O or [Fe(phen)<inf>3</inf>]sq·8H<inf>2</inf>O, where phen is 1,10-phenanthroline and sq is the squarate dianion (C<inf>4</inf>O <inf>4</inf>)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 O <inf>water</inf>-H⋯O, O<inf>water</inf>-H⋯O<inf>water</inf> and C-H⋯O hydrogen-bonding interactions is responsible for crystal stabilization. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
