摘要：
A layer coordination polymer of [Sr(H2MIDC)(2)(H2O)(2)](n), (H3MIDC = 2-methyl-1H-imidazole-4,5-dicarboxylate) has been synthesized and characterized. Single X-ray structural analysis indicates the title compound crystallizes in a monoclinic lattice, P2(1)/n with a = 6.902(1) b = 14.469(3), c = 16.641(3) angstrom, = 98.58(3)degrees, Z = 4, V = 1643.2(6) angstrom(3), (c) = 1.867 g/cm(3), F(000) = 928, S = 1.079, R-1 = 0.1346, wR(2) = 0.3892 (CIF file CCDC no. 791212). Crystal structure analysis reveals that Sr2+ ion is eight-coordinate and lies in a bicapped tetragonal bipyramid environment with one nitrogen atom and seven oxygen atoms. For the variaties of the ligand's coordination modes and the bridging oxygen atom in carboxylate group, the structure presents a two-dimensional layer molecular network. This coordination polymer exhibited intense fluorescent emissions in the solid state at room temperature.
