Abstract:EXAFS spectroscopy was used to study the influence of various factors on the structure of PdCl2 complexes with organic sulfides in organic solvents. Absolute interatomic distances in the first coordination sphere of Pd were determined for the complexes PdCl2·2(C6H13)2S] (I), PdCl2·(C6H13)2S]2 (II), PdCl2·2(C6H5)2S] (III), and PdCl2·(C4H9)S(C4H7)] (IV) and for their solutions in some organic solvents. Our hypothesis that aromatic solvent molecules are coordinated to palladium atoms through weak π-bonds, which was proposed for complex (I) in benzene, is supported fror benzene and pseudocumene solutions of complexes (I), (II), and (III). It is shown that the characteristic features of the specific solvation of the complexes under study are determined by the electron properties and spatial structures of the molecules as well as by the donating abilities of the solvents.
