摘要
配合物MoO2(OC6H4CHNCH2CH2S)和Mo(SC6H4NH)3在溶剂CH2Cl2中与I2的加合作用通过UV光谱进行考察,大约在290nm呈现一强的电荷迁移吸收峰.360nm附近出现碘的蓝移峰,电荷转移加合物摩尔比是1:1。分离出Mo(SC6H4NH)3·I2·2.5CH2Cl2和Mo(SC6H4NH)3·2I2的固体加合物,利用红外光谱对其进行表征。
Additive reactions of complexes MoO2(OC6H4CHNCH2CH2S) and Mo(SC6H4NH)3 with iodine were detected by UV spectroscopy in dichloromethane solution. Their UV spectra bring about a very strong charge-transfer band near 290 nm and a blue-shifted band of iodine near 360 nm, when the solution of complexes is mixed with iodine solution equivalently. The molar ratio of two complexes to iodine are equaled to 1: 1. Two solid state adducts of Mo(SC6H4NH)3. I2 . 2. 5CH2Cl2 and Mo(SC6H4NH)3. 2I2 have been separated. The infraled spectra of these solid state adducts exhibit no great difference from that of complex Mo(SC6H4NH)3.
