摘　　要：The light-oxidation degradation processes of Zn(dmid)(phen)_2 ( dmid = 4,5-dimercapto-l, 3-dithiole-2-one, phen = 1,10-phenanthroaline) in pyridine solvent has beenmonitored. It has been found under the light, dmid^(2-) of Zn(dmid)-(phen)_2 in pyridine solutioncould generate NCS~ and NCS^-replaces dmid^(2-) to form Zn(NCS)_2 (phen)_2 simultaneously. Thecrystal structure of Zn(NCS)_2 (phen)_2 has been determined. In the crystal of Zn(NCS)_2 (phen)_2,two NCS~ ligands are arranged in syn-configuration, and there is strong pi-pi interaction betweenthe two adjacent parallel phen.The light-oxidation degradation processes of Zn(dmid)(phen)_2 ( dmid = 4,5-dimercapto-l, 3-dithiole-2-one, phen = 1,10-phenanthroaline) in pyridine solvent has beenmonitored.
