摘要：
A novel tetranuclear manganese(II/III) complex with anions of pyridine-2,6-dicarboxylic acid (dipicolinic acid) has been synthesised and magneto-structurally characterised. The crystal structure of [Mn-II Mn-2(III) (2)-(dipic)(6)(H2O)(4)].2CH(3)OH . 4H(2)O has been determined by single-crystal X-ray diffraction. The tetranuclear complex molecule [Mn-II Mn-2(III) (2)(dipic)(6)(H2O)(4)] is centrosymmetric and two manganese(II) and two manganese(III) atoms are bridged by four dipicolinate ligands. The complex molecules and uncoordinated water and methanol molecules are connected through hydrogen bonds and they form a 3D supramolecular hydrogen-bonding network.
