Synthesis,Structure,and Surface Photo-electric Properties of a New Zn(Ⅱ) Coordination Complex Constructed from 2-(1H-benzotriazol-1-yl)acetic Acid and 1,10-Phenanthroline Ligands

A new binuclear Zn~Ⅱ coordination complex,Zn_2(bta)(phen)_2(Cl)_3(1,Hbta = 2-(1Hbenzotriazol-1-yl)acetic acid and phen = 1,10-phenanthroline),has been synthesized and characterized by single-crystal X-ray diffraction,IR spectroscopy,elemental,and photoluminescent analysis.Complex 1 crystallizes in triclinic system,space group P1 with a = 9.3040(19),b = 10.694(2),c =16.841(3) ?,α = 101.18(3),β = 105.77(3),γ = 91.72(3)°,V= 1575.8(5) ?~3,C_(32)H_(22)Zn_2Cl_3N_7O_2,M_r =773.66,D_c = 1.631 g/cm~3,Z = 2,F(000) = 780,μ = 1.820 mm~(-1),the final R = 0.1238 and wR =0.1131.X-ray diffraction analyses indicate that 1 displays two crystallographic independent Zn~Ⅱmetal centers with a distorted tetragonal pyramidal(ZnN_4O) and a tetrahedral(ZnNCl_3) geometries,respectively.The phen serves as a common N,N'-bidentate ligand,and the bta~- as a unique N,O-bridged ligand in 1.In the crystal,1 forms a stable 3D supramolecular architecture by trifurcated hydrogen bonding C-H…C1 interactions and C-H…π,π…π stacking.1 showed photo-electric conversion properties.
