Single crystals of a new calcium(II) complex of benzilic acid, [Ca(C14H11O3)2(C14H12O3)2] have been successfully grown by gel diffusion technique at room temperature. Single crystal X-ray diffraction study reveals that the compound belongs to orthorhombic system with space group Fddd. The adjacent CaO8 units are linked via O–H–O interaction to form one dimensional polymeric chains. The extensive hydrogen bonding interactions lead to a supramolecular structure. The grown crystals were further characterized by elemental analysis, FT-IR, UV–Visible, thermogravimetric, powder X-ray diffraction and solid state photoluminescence studies. 相似文献

A novel one dimensional coordination polymer of Cd(II) with thiophene-2,5-dicarboxylic acid (H2tdc), {[Cd(tdc) (H2O)3]·1.5H2O}n has been prepared by gel diffusion method. Elemental analysis, single crystal and powder X-ray diffraction studies, FT-IR and UV–visible spectral studies were used to characterize the title compound. Cd-thiophene units form a linear chain in the crystal structure. Thiophene rings of a linear chain are stacked parallel to each other while the thiophene rings of the adjacent chains are intercalated and stacked ant-parallel to each other. Extensive hydrogen bond formation and π-π interactions between thiophene moieties are responsible for the supramolecular architecture. TG/DTG studies confirm the presence of both lattice and coordinated water molecules. Photoluminescence studies showed that the title compound is red shifted by 46 nm compared to ligand. 相似文献
