Three manganese(II) binuclear complexes have been synthetized, namely [Mn2(NAPH)(L)4(ClO4)2, L is bpy(2,2'-bipyridyl), phen(1,10-phenanthroline) or NO2-phen(5-nitro-1,10-phenanthroline), NAPH denotes the 1,8-naphthalate dianion. Based on IR, elemental analyses nd conductivity measurement, these complexes are proposed to have extended NAPH-bridges structures and consist of two manganese(II) in a distorted octahedron environment. The temperature dependence of magnetic susceptibilities of manganese(II) complexes have been studied, giving the exchange integral J=-0.36 cm-1 (bpy); J=-0.49 cm-1 (phen), respectively. These results indicate a weak antiferromagnetic coupling between the paramagnetic ions in the complexes.
