Özet
Three new metal organic coordination architectures from one-dimensional structures to three-dimensional frameworks, formulated as [Zn(μ-HCO2)(HCO2)(μ-o-bix)]n (1), {[Cu(μ-o-bix)2(H2O)2]·2HCO2}n (2) and {[Cd2(μ3-sip)2(μ-o-bix)2Cd(μ-o-bix)2(H2O)2]·5H2O} (3) (sip = 5-sulfoisophthalate), were synthesized using the flexible 1,2-bis(imidazole-1-ylmethyl)-benzene (o-bix) ligand in mixed-solvent media (solvothermal conditions) and characterized by single-crystal diffraction, FT-IR and photoluminescence spectroscopy and thermogravimetric/differential thermal analysis. The X-ray crystallographic studies of 1 and 2 reveal 2D layer structures involving formate ions, which are generated in situ from the hydrolysis of DMF. Topological analysis results of the complexes show that 1 displays a honeycomb-like 63 layer and 2 has a hydrogen-bonded 2D structure with a 4-connected {44·62} square lattice topology. Compound 3 exhibits a 3D 4,6-connected tcj/hc {42·52·62}{42·56·64·73} net. In addition, the photoluminescence spectra of 1 and 3 show blue fluorescent emission bands; these emissions can probably be assigned to intraligand fluorescent emissions.
