PHOTOREDOX DECOMPOSITION OF TIN(II), LEAD(II), ANTIMONY(III) AND BISMUTH(III) IODIDE COMPLEXES IN SOLUTION

摘要

The main group metal complexes SnI3-, PbI3-, SbI4- and BiI4- display long-wavelength absorption bands which are assigned to sp/LMCT transitions. The photochemistry of these complexes is determined by the CT character of their lowest-energy excited state. The photolysis in acetonitrile leads to a photoredox decomposition which yields I-3(-) and the elemental metals as final products. The results of the continuous photolysis are supplemented by observations on the flash photolysis of PbI3-. [References: 16]
