Abstract
CdK EXAFS and113Cd NMR spectra were measured for solutions of cadmium 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 atoms for complex forms in solutions were determined from EXAFS data using the EXCURV- 92 package. 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- C4H9)2NCS2]2. For the tributylphosphine solution of Cd[(n- C4H9)2NCS2]2, additional coordination of the phosphorus atoms of tributylphosphine molecules by cadmium is established.
