摘要：

Solid-state rearrangements of trans-RuCl2(RNC)4 (trans-1) or ttt-RuCl2(RNC)2(PR'3)2 (ttt-2) to cis-RuCl2(RNC)4 (cis-1) and tcc-RuCl2(RNC)2(PR'3)2 (tcc-2) and their electrochemical reactions were examined. The enthalpy of the trans-1 to cis-1 isomerization is smaller than that of ttt-2 to tcc-2 isomerization and these isomerizations proceeded to the thermodynamically more stable isomers. Electrochemical oxidations of these complexes were quasi-reversible and the oxidation potentials of trans and ttt isomers are smaller than those of cis and tcc isomers, respectively. These results were discussed in relation to the results of EHMO calculations.
