UDC 546.712+547.32
Keywords:
manganese, crystal structure, EPR spectroscopy, magnetic propertiesAbstract
Dinuclear manganese(II) complex with formula [Mn2(piv)4(phen)2]∙H2O, where piv – pivalate (CH3)3CCO2–, phen – 1,10-phenanthroline was synthesized by the reaction of oxidative dissolution of metal. Weak antiferromagnetic interaction are present between two Mn centres in dimmer. To estimate the energy order of this probable interaction, density-functional theory calculations were performed. Dimmers are not stable in the solutions as it was demonstrated by EPR spectroscopy.
