| Abstract: | Four novel coordination compounds, namely, Cd2(pydc)2(bpp)2(H2O)2]? bpp?2H2O (1), Zn(Hpydc)2]?3H2O (2), Cd(dhb)2(phen)2] (3), and Zn(L)(phen) (H2O)] (4) (H2pydc?=?2,6-pyridinedicarboxylic acid, Hdhb?=?2,6-dihydroxybenzoic acid, H2L?=?5-((2'-cyano-1,1'-biphenyl-4-yl) methoxy)isophthalic acid, bpp?=?1,3-bis(4-pyridyl)propane, and phen?=?1,10-phenanthroline) have been hydrothermally synthesized and characterized by IR spectroscopy, thermogravimetric analysis and X-ray single crystal diffraction analyses. Compounds 1, 2 and 3 feature zero-dimensional (0D) structures and 1 is further extended to one-dimensional (1D) chain structure through C-H???O hydrogen bonding interactions. Compound 4 exhibits 1D chain structure. The luminescent properties of compounds 3 and 4 have also been studied. |
