摘要：
The interaction of iodine with the nitrogen cyclic base 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane (TMTACTD) is studied spectrophotometrically in CHCl3 and the resonance Raman spectrum of the solid product is recorded. The results indicate the formation of the polyiodide species with the formula [(TMTACTD)I](+). I-9(-). The resonance Raman spectrum of the product suggests that the enneaiodide, I-9(-), does indeed contain the I-5(-) unit and this implies that I-9(-) exists as (I-5(-)) (2I(2)) where the I-5(-) portion has a bent configuration with C-2v symmetry. All bond vibrations for the I-5(-) and I-2 units are observed and assigned.
