- 中文摘要: A new complex of [Rh(PA)2Cl2]Cl·H2O (where PA = phenyl-pyridin-2-ylmethylene-amine) has been synthesized and characterized. The complex shows high intensity bands in the UV region, and these are assigned to spin-allowed p-p* transitions. The medium-intensity absorption band profile in the lower energy region can be explained by convolution of spin-allowed CT and d-d* transitions. Emission spectrum at low temperature (77 K) of the complex in EtOH/MeOH (4:1 v/v) has also been investigated. It shows a broad, symmetric, and structureless red emission with microsecond lifetime and hence is assigned as d-d* phosphorescence. Voltammetric data have also been obtained for the complex. There were three reduction peaks observed for the complex. The first peak, including two reduction steps with elimination of two chlorides, is consistent with ECEC reaction.
