(2,9-Dimethyl (Pyridine-2,6 6)Copper(II) Trihydrate

Abstract

The copper(II) centre in the mononuclear title complex, [Cu(C <inf>7</inf>H<inf>3</inf>NO<inf>4</inf>)(C<inf>14</inf>H<inf>12</inf>N <inf>2</inf>)]·3H<inf>2</inf>O, is surrounded by one bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and one tridentate pyridine-2,6-dicarboxylate ligand, and exhibits a distorted square-pyramidal geometry. The crystal packing involves both hydrogen-bonding and π-π interactions. The solvent water molecules link monomers to one another through hydrogen-bonding interactions, forming ladder-like chains in the bc plane. Face-to-face and slipped π-π interactions also occur between dmphen rings of neighboring molecules and are responsible for interchain packing. © 2005 International Union of Crystallography.
