以Mo(CO)_■和TPPS为原料,在DME溶剂中合成羟基—氧钼(Ⅴ)—(5,10,15,20-四-4-磺酸苯基卟啉)配合物(Mo(Ⅴ)O(OH)TPPS)。对配合物进行紫外可见光谱、电子自旋共振谱和激光拉曼光谱的表征,并用HMO法计算配合物主配体共轭体系Ⅱ分子轨道能级和对称性。由电子自旋共振谱,紫外可见光谱和HMO法计算,推测配合物在酸性水溶液中为C_(4■)对称性的单体Mo(Ⅴ)O(OH)TPPS,而在碱性水榕液中则是D_(2h)点群的二聚体[Mo(Ⅴ)O(OH)TPPS]_2,但是它的一半仍被视为C_(4■)对称性。而在中性水溶液中两者共存。
Mo (CO) _ ■ and TPPS as raw materials, in the DME solvent hydroxy - molybdenum (V) - (5,10,15,20-tetra-4-sulfonic acid phenyl porphyrin) V) O (OH) TPPS). The complexes were characterized by UV-visible spectrum, electron spin resonance spectrum and laser Raman spectrum. The orbital energy levels and symmetries of the complex ligands were calculated by HMO method. The results of electron spin resonance spectrum, UV-vis spectrum and HMO method indicate that the complex is a C 4 4 symmetrical monomeric Mo (V) O (OH) TPPS in acidic aqueous solution, Is the dimer [Mo (Ⅴ) O (OH) TPPS] _2 of D_ (2h) point group, but half of it is still regarded as C_ (4_) symmetry. Both coexist in a neutral aqueous solution.
