MAGNETIC BEHAVIOR OF LAMELLAR MnPS3 AND CdPS3 COMPOSITES WITH A PARAMAGNETIC MANGANESE(III) MACROCYCLIC GUEST

MAGNETIC BEHAVIOR OF LAMELLAR MnPS3 AND CdPS3 COMPOSITES WITH A PARAMAGNETIC MANGANESE(III) MACROCYCLIC GUEST

Six new composites derived from the intercalation of the MPS3 phases (M = MnII, CdIII) with the macrocyclic manganese(III) complex [MnL(H2O)2].NO3(H2O) (LH2 = Schiff base macrocyclic ligand derived from the condensation of 2-hydroxy-5-methy1-1,3-benzene-dicarbaldehyde and 1,2-diamine-benzene) were o...
