✦ Synopsis

Three new polynuclear Mn II complexes with chloroacetate bridges were obtained and characterized by X-ray diffraction: 2), and [Mn(µ-ClCH 2 COO) 2 (phen)] n (3). The Mn•••Mn distance for 1 (3.624 A ˚) is smaller than for 2 (4.613 A ˚) and 3 (4.530 A ˚); this is in agreement with the number of carboxylate bridges. The three compounds show a weak antiferromagnetic coupling. The J values are -3.82 cm -1 for
