Syntheses, structures, and magnetic properties of a series of Mn–M–Mn trinuclear complexes with different spin configurations

Abstract

A series of trinuclear complexes, [MnII2YIII(L)2(HL)2(NO3)3][YIII(NO3)5]·7H2O (1'), [MnII2GdIII(HL)4(NO3)4]2[MnII2GdIII(L)(HL)3(NO3)4][GdIII(NO3)5]4·2(o-Xy)·12H2O (2') and [MnII3(L)(HL)2(NO3)4](NO3)·1.25(p-Xy) (3'), were synthesized by using a β-diketone ligand HL (HL = 1,3-bis(pyridin-2-yl)propane-1,3-dione). X-ray structural analyses revealed each complex has...
