| Abstract: | The hydrothermal reaction of 1,2-dicyanobenzene with NaN3 in the presence of Cd(NO3)2 affords a novel 2D cadmium tetrazolyl-benzoate, {Cd(tzbz)(H2O)}n (H2tzbz is 2-(5-tetrazolyl)-benzoate). The tzbz ligand is generated in situ through the [2+3] Sharpless cycloaddition reaction and hydrolyzation. Its crystal structure was determined by single-crystal X-ray diffraction method. The crystal crystallizes in the orthorhombic system, space group Pbca with a = 9.6659(19), b = 7.6366(15), c = 25.964(5)(A), V= 1916.5(7) (A)3, Z= 8, Mr = 318.57, Dc =2.208 g/cm3, F(000) = 1232 and μ = 2.276 mm-1. The Cd(Ⅱ) atom is coordinated by four tzbz ligands and one water molecule to form a severely distorted pentangle bipyramid. While each tzbz ligand connects to four Cd(Ⅱl) atoms in aμ4-ηl, η2, η1, ηl, η1 coordination mode to construct a 2D architecture of the title complex. Additionally, the title complex exhibits strong fluorescence at room temperature in the solid state. |
