  • A new binuclear ZnII coordination complex, Zn2(bta)(phen)2(Cl)3 (1, Hbta = 2-(1H- benzotriazol-1-yl)acetic acid and phen = 1,10-phenanthroline), has been synthesized and characteri- zed by single-crystal X-ray diffraction, IR spectroscopy, elemental, and photoluminescent analysis. Complex 1 crystallizes in triclinic system, space group P with a = 9.3040(19), b = 10.694(2), c = 16.841(3) Å, α = 101.18(3), β = 105.77(3), γ = 91.72(3)°, V = 1575.8(5) Å3, C32H22Zn2Cl3N7O2, Mr = 773.66, Dc = 1.631 g/cm3, 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 ZnII metal centers with a distorted tetragonal pyramidal (ZnN4O) and a tetrahedral (ZnNCl3) 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…Cl interactions and C-H…π, ππ stacking. 1 showed photo-electric conversion properties.
