摘要：
The absorption and emission spectra of GeCl3-, SnCl3-, PbCl3-, and PbCl42- in acetonitrile were recorded. In addition, emission quantum yields and lifetimes were determined. The emitting excited states are of the metal-centered sp type and originate from the 3P State of the free s2 ions. It is suggested that the complex ions which have trigonal-pyramidal C3v (MC13-) and seesaw C2v (PbCl42-) structures in the ground state rearrange toward trigonal-planar D3h and tetrahedral T(d) geometries, respectively, in their sp excited states.
