Abstract

CdK EXAFS and 113Cd NMR spectra, ZnK EXAFS and XANES spectra were measured for solutions of cadmium and zinc dialkyldithiocarbamates in organic solvents with different donor numbers: tributylphosphine, methylene chloride, benzene, dibutylsulfide, pyridine, dimethylsulfoxide and for some model compounds. The parameters of the local surroundings of the Cd and Zn atoms for complex forms in solutions were determined using EXAFS . Spatial structure models of the complex forms in a metal chelate - nonaqueous solvent system are suggested. It is established that coordination of nitrogen atoms by cadmium atoms in pyridine solutions is realized for both Cd[(C2H5)2NCS2 ]2 and Cd[(n−C4 H9)2NCS2]2. For the tributylphosphine solution of Cd[(n−C4H9) 2NCS2]2 and Zn[(n−C4H9)2NCS2]2, additional coordination of the phosphorus atoms of the solvent molecules by the metal atoms are established.
