The Product was characterized by UV、ESR and Raman Spectra. Thc Π molecular orbital energy levels was calcalated by HMO method. Both the experiments and HMO Calculation show that the coordination compound exists in a few different forms in aqueous solution with different PH values The coordination compound is in mourner Mo（V）O（OH）TPPS with C 4 , Symmetry in acidic aqueous solution The Coordination compouna is in dimer[Mo（V）O（OH）TPPS] 2 wibh D 2A symmetry in basic aqueous solution. But there is a monomer-dimer equilibriun accompanied by change of PH values. 2Mo（V）O（OH）TPPS■[Mo（V）O(OH(TPPS] 2 过渡金属配合物 大环配体 钼卟啉 HMO法 transition metal coordination compound macrocyclic ligand Porphynn of molybdenum the Huckel molecular orbital method 中国科学院科学基金 1989-02-01 2021-04-01 2
