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).
