Tris(1,10-Phenanthroline)nickel(II) Squarate Octahydrate

Abstract

In the title mononuclear [Ni(phen)<inf>3</inf>]sq·8H<inf>2</inf>O complex [phen is 1,10-phenanthroline (C<inf>12</inf>H<inf>8</inf>N<inf>2</inf>) and sq is squarate (C<inf>4</inf>O<inf>4</inf>2-], the Ni II ion has a distorted octahedral coordination geometry composed of six N atoms from 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.
