Trinuclear manganese(II) complexes of the compositions [Mn3(phen)6(ttc)](ClO4)3 (1), [Mn3(dmbpy)6(ttc)](ClO4)3∙ 2H2O (2) and [Mn3(bpy)6(ttc)](ClO4)3∙ 3H2O (3), where phen = 1,10-phenanthroline, dmbpy = 4,4′-dimethyl-2,2′-bipyridine, bpy = 2,2′-bipyridine and H3ttc = trithiocyanuric acid (2,4,6-trimercapto-1,3,5-triazine), were prepared and characterized by elemental analysis, FTIR and Raman spectroscopies, MALDI-TOF mass spectrometry, magnetic and conductivity measurements. The magnetic analysis incorporating simultaneous fitting of the temperature dependence and the field dependence of the magnetization using the isosceles triangle spin Hamiltonian model revealed a weak antiferromagnetic exchange within the trinuclear units.
