Resumo[Mn2(Hsal)4(H2O)4] reacts with an excess of 2,2′-bipyridine (bipy) and 1,10phenathroline (phen) to give the manganese(II) complexes [Mn(Hsal)2(bipy)] · H2O (1) and [Mn(Hsal)2(phen)] (2), respectively. The X-ray crystal structure of 1 shows it to be polymeric, with Mn0.5(Hsal)(bipy)0.5 · (H2O)0.5}n as the asymmetric repeat unit in the polymer chain. In the presence of added imidazole, 1 and 2 both vigorously calalyse the disproportionation of hydrogen peroxide.
