Abstract
Four new two and three dimensional coordination polymers, namely, [Co2(µ4-L)(µ-obix)2]n (1), [Zn2(µ4-L)(µ-obix)2]n (2), {[Zn2(µ4-L)(µ-obix)2]·2CH3CN}n (3), and {[Cd2(µ4-L)(H2O)4(µ-obix)]n·2H2O}n (4), where H4L = 5,5′-(but-2-ene-1,4-diylbis(oxy))diisophthalic acid and obix = 1,2-bis((1H-imidazol-1-yl)methyl)benzene), were synthesized under solvothermal conditions. Their structures have been determined by single-crystal X-ray diffraction analyses, infrared spectra (IR) and elemental analyses. Compounds 1 and 2 were isostructural and displayed 3D 3-fold interpenetrating frameworks with mog moganite topologies. Compound 3 featured a 2D 2-fold interpenetrating network with 3,4L13 topology. Compound 4 exhibited a 2D layer structure with 3,4-connected 3,4L13 topology. Furthermore, luminescence and thermal properties of the compounds were investigated in detail.
