摘要
A new Cd(II) coordination polymer, [Cd-0.5(nba)(bib)(0.5)](2n) (1, Hnba = 4-nitrobenzoic acid, bib = 1,4-bis(imidazol-1-yl)-butane), was synthesized at room temperature condition and characterized by IR spectra, elemental analyses, single-crystal and powder X-ray diffractions. Complex 1 belongs to the monoclinic system, C2/c space group, with a = 26.0600(14), b = 6.7889(4), c = 16.5825(9) angstrom,beta = 118.8120(10)degrees, V= 2570.6(2) angstrom(3), Z = 4. It shows one-dimensional chains and is further linked by pi-pi stacking interactions to yield a three-dimensional supramolecular structure. Thermal stability and luminescence of 1 were investigated.
