Darstellung und Charakterisierung von Halogeno(diethyldithiocarbamato) (triethylphosphin)-nickel(II)-Komplexen

摘要

The complexes Ni(PEt3)2dtcX(1) and Ni(PEt3)Xdtc(2) (dtc=S2CNEt2,X=Cl, Br, I) have been prepared. As conductivity, susceptibility, UV and IR measurements show, the cations Ni(PEt3)2dtc+of1and the complexes2at ambient temperature have square-planar structure. We suppose there might exist an equilibrium for2between square-planar and tetrahedral configuration.
