“…The 3 "P -" 3 Cd spin-spin coupling constant is 1629 Hz for the complex with two TBP molecules and 1523 Hz for the complex with one TBP molecule; this corresponds to the value given in [20]. The rate of exchange increases with concentration of pyridine in solution, and methylene chloride, evidently, also participates in solvate formation.…”

CdK EXAFS and " 3 Cd 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[(C 2 H,) 2 NCS 2 ] 2 and Cd[(n-C 4 H 9 ) 2 NCS 2 ] 2 . For the tributylphosphine solution of Cd[(n-C 4 Hg) 2 NCS2] 2 and Zn[(n-C 4 H 9 ) 2 NCS2] 2 , additional coordination of the phosphorus atoms of the solvent molecules by the metal atoms are established.

“…Features A, B and C shows clearly visible changes of their sharpness, shape, position and intensity indicating variations of Zn atoms surrounding geometry and symmetry in solutions. Possibility of Py and TBP molecules coordination by Zn atoms in solutions is supported by the existence of solid compounds with 4S+2N and 4S+P Zn atoms surroundings such as ZnLI2(1,10-phenanthroline) (Bell et el., 1989) and ZnL2P(Alkyl)3 (Zeng et al, 1994) complexes. ZnK XANES spectra measured on solid i ZnL 2(1,10-phenanthroline) complex and its solutions are not presented in the paper because all of them are identical.…”

CdK EXAFS, ZnK and CuK EXAFS and XANES spectra were measured for solutions of cadmium, zinc and copper dialkyldithiocarbamates in organic solvents with varying donating abilities: benzene, pyridine, tributylphosphine and for some model compounds. The parameters of the local surroundings of the Cd, Zn and Cu atoms for complex forms in solutions were determined using EXAFS spectroscopy. Spatial structure models of the complex forms in a metal chelate -nonaqueous solvent system are suggested.

“…Simple dialkyldithiocarbamates of zinc and cadmium have dimeric structures in the solid state. The parent dimeric dithiocarbamates can be broken into monomeric species by adduct formation, as illustrated by recent structural studies of the 2,2'-bipyridyl [2], 1,lOphenanthroline [2] and triethylphosphine [3] adducts of Cd(S2CNEt& and 1,2-bis(diethylphosphiino)ethane adducts of zinc and cadmium bis(diethy1-dithiocarbamates) [3]. However, this is not the case for the N,N,M, N-tetramethylethylenediamine (TMED) adduct of the asymmetric dithiocarbamate species Zn(S2CNMe'Pr)2 which was reported as consisting of two bis(N-methylisopropy1dithiocarbamato)zinc molecules bridged by a TMED molecule [4].…”

The crystal structure of the title complex 2[R2NCS&. Zn(4,4'-bipy) (R = Piperidyl), 1, revealed that it consists of dimers made up from two crystallographically independent molecules. Each zinc atom in 1 forms a Scoordinate pseudo-square-based pyramidal arrangement (with four Zn-S and one Zn-N interactions). Bondlengths to Zn with the coordinating atoms are comparable to those in other Zn(1I) dithiocarbamate complexes. The piperidine ring has a chair conformation. To allow improved packing, the title complex molecules form an approximately linear arrangement extending along both a and 6. TGA showed that 1 is decomposed in two close steps to produce ZnS as identified by residual weight. The complex 1 crystallizes in the monoclinic space group C2 cwithcellparameters: a=22.021(5), 6=22.215(3), c= 17.537(2) A, p=93.49(2)", V = 8563(3) i3 and 2 = 8 . The structure was refined by full-matrix least-squares methods to R = 0.067, Rw = 0.1 14.
