• photoluminescence

A cadmium(II) coordination polymer [CdL(H2O)] (1) (H2L = 3,3-bis(carboxymethyl)imidazo[1,2-a]pyridin-2-one) was synthesized under hydrothermal conditions and characterized by X-ray structure analysis. Compound 1 crystallizes in the monoclinic space group P2(1)/n with a = 11.945(2) angstrom, b = 8.0865(16) angstrom, c = 13.114(3) angstrom, beta = 91.36(3)degrees, Z = 4, and represents a 2D network with the 4* 8(2) topology constructed from combination of metal centers with a T-shaped geometry and ligands with T-shaped structure simultaneously. Compound 1 also exhibits strong photoluminescence at room temperature.
