摘　　要：A novel coordination polymer {[Zn（ts-gln）（bipy）].3H2O}n （ts-glnH2 = N-p-tolysulfonyl-glutamine, bipy = 2,2′-bipyridine） has been prepared and structurally characterized by X-ray diffraction method. It crystallizes in orthorhombic, space group P212121 with a = 8.2622（5）, b =16.6244（10）, c = 18.2807（10） A, V = 2510.9（3） A^3, C22H2N4O8SZn, Mr = 573.91, Z = 4, Dc = 1.518 g/cm^3, μ（MoKα） = 1.115 mm^-1, F（000） = 1192, the final R = 0.0262 and wR = 0.0662 for 5691 independent reflections with Rint = 0.0240. The zinc（Ⅱ） atom is coordinated by N（3） and N（4） atoms of a bipy molecule, two carboxylate O（1） and O（2A） and amino N（ 1 ） atoms of ts-gln ligands, resulting in a square-pyramidal geometry. The title complex consists of an infinite zigzag chain of zinc（Ⅱ） ions linked by the carboxylate of N-p-tolysulfonyl-glutamine.A novel coordination polymer {[Zn（ts-gln）（bipy）].3H2O}n （ts-glnH2 = N-p-tolysulfonyl-glutamine, bipy = 2,2′-bipyridine） has been prepared and structurally characterized by X-ray diffraction method.
