摘要：
The complexes CdL4(ClO4)(2) (1), CdL2(NO3)(2) (2), and CdL2Cl2 (3) (L = (Me2N)(3)P(Se)) have been prepared and characterized by elemental analysis, conductivity measurements, IR, and multinuclear (P-31, Se-77, and Cd-113) NMR spectroscopy. P-31 and Se-77 NMR data were informative of changes associated with complex formation. The structure of the prepared complexes was further confirmed in solution by their Cd-113 NMR spectra, which show a quintuplet for the perchlorate complex and a triplet for each of the nitrate and chloride complexes due, respectively, to coupling with four and two equivalent phosphorus atoms, consistent with a four coordinate tetrahedral geometry for the cadmium center. The NMR data are discussed and compared with those reported for related complexes.
