| 摘 要： | <正>A new metal-organic coordination polymer[Zn_2(dpphen)_2(H_2btec)(btec)_(0.5)]_n (dpphen=4,7-diphenyl-1,10-phenanthroline,H_4btec=1,2,4,5-benzenetetracarboxylic acid)1 was obtained via hydrothermal synthesis and characterized by elemental analysis,TG,IR spectrum and single-crystal X-ray diffraction.The complex crystallizes in the monoclinic system,space group P2_l/n with a=16.2996(14),b=14.3332(12),c=25.247(2)(?),β=103.4050(10)°,V=5737.7(9)(?)~3, C_(63)H_(37)N_4O_(12)Zn_2,M_r=1172.71,D_c=1.358 g/cm~3,μ(MoKα)=0.902 mm~(-1),F(000)= 2396,Z=4, the final R=0.0684 and wR=0.1281 for 3728 observed reflections(I2σ(I)).It exhibits a two-dimensional network structure constructed by mixed ligands of dpphen and H_2btec/btec.
