| dc.description.abstract | The synthetic details and characterization data of three mononuclear complexes or the type [Cd(dpa)2X2] (dpa = 2,2'-dipyridylamine; X = N3-, NCS-, 2 and X-NCO-,3) are described. In one case, [Cd(dpa)2(NCS)2 (2), X-ray structure determination has been made for the exact definition of the coordination sphere. Structural analysis reveals that the cadmium(II ) centre is in a distorted octahedral environment with a CdN5S chromophore with two dpa units roughly perpendicular to one another and the two thiocyanates in mutual cis orientation with one in S-bound and the other in N-bound states. The mononuclear unit packs through N-H ... S and N-H- ... N hydrogen bonding to have a one-dimensional (ID) chain. Spectroscopic and other physicochemieal data show that compounds 1 and 3 have the cognate structure. The compounds display high energy intraligand 1(π- π *) fluorescence and intraligand 3(π- π *') phosphorcscence in glassy solutions (DMF at 77 K). A band (near 375 nm) observed for all the complexes in their solid state emission spectra is an excimeric emission. The role of dpa, a tailored diimine with active amine hydrogen and aromatic pyridine ring, is discussed towards functionalisation on crystal engineering and luminescence behaviour. | en_US |
