激光烧蚀CuCl_2或CuCl靶的产物与O_2或N_2共同沉积在11K的Ar基质中,在1175.0cm~(-1)(O_2/Ar)和2296.3cm~(-1)(N_2/Ar)处观察到了新的红外吸收.通过同位素取代实验以及量子化学计算,可将1175.0cm~(-1)归属为ClCu(η~2-O_2)的O—O伸缩振动,而将2296.3cm~(-1)归属为ClCuNN的N—N伸缩振动.ClCu(η~2-O_2)和ClCuNN这两种新型配合物的确证,为进一步研究含O_2,N_2的过渡金属配合物提供了一种模型分子.
Laser ablated CuCl_2 or CuCl targets were deposited together with O_2 or N_2 in 11K Ar matrix and observed at 1175.0cm -1 O_2 / Ar and 2296.3cm -1 N_2 / Ar To a new infrared absorption. By isotope substitution experiments and quantum chemical calculations, the 1175.0cm -1 O-O stretching vibration assigned to ClCu (η ~ 2-O_2) N-N stretching vibration assigned to ClCuNN.The confirmation of two new complexes, ClCu (η ~ 2-O_2) and ClCuNN, provides a model molecule for the further study of transition metal complexes containing O_2 and N_2.
