A [MnIII2O(MeCO2)2(H2O)2(bipy)2]2+(bipy = 2,2′-bipyridine) unit with accessible co-ordination sites. Contribution to the modelling of the photosynthetic oxygen evolving centre
Abstract
A new MnIII binuclear system with an oxo-bis(acetato) bridge and water co-ordinated to the Mn ions has been synthesized, crystallographically characterized, and its antiferromagnetic coupling measured (singlet–triplet gap 6·8 cm–1).
