Abstract

Treatment of an aqueous suspension of Cu(OH)2 and 2,2′-bipyridine (bipy) with either Na2HAsO4· 7H2O (1[1[2) or As2O5 (1[1[1) yields single crystals of {](bipy)Cu(μ-H2AsO4)(H2AsO 4)[2}n, 1, on standing. The solid-state structure of 1 consists of a three dimensional supramolecular network, supported by a combination of coordination covalent, hydrogen bonding and face-to-face π-π interactions. Variable temperature magnetic susceptibility measurements reveal very weak antiferromagnetic coupling between Cu(ii) centres across the dihydrogen arsenate bridges (J = -0.58 cm-1).
