Tetranuclear manganese(ii) complexes of sulfonylcalix[4]arene macrocycles: synthesis, structure, spectroscopic and magnetic properties†
Abstract
Two tetranuclear manganese(II) complexes {K+[Mn4(ThiaSO2)2(OH)]−} (1) and {K+[Mn4(ThiaSO2)2(F)]−} (2) have been synthesized under solvothermal conditions in
