摘要：

Mercury(II) complexes of 1,10-phenanthroline (phen) and 2,2'-bipyridine (bipy), [Hg(phen)(2)(SCN)(2)] (1), [Hg(2,2'-bipy)(2)(SCN)(2)] (2) and [Hg(phen)(2)(NO3)(2)] (3) have been synthesized and characterized by elemental analysis, IR, H-1 NMR and C-13 NMR spectroscopy. The thermal stability of 1-3 were studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The structure of 1 has been confirmed by X-ray crystallography. The complex is a monomer and the Hg atom has an unsymmetrical six-coordinate geometry, formed by four nitrogen atoms of the two phen ligands and two sulfur atoms of the two thiocyanate anions. Solid-state luminescent spectra of phen, 2,2'-bipy and 1-3 indicate emission with the maximum intensity at ca 467 nm upon excitation at 295 nm.
