Two novel mononuclear complexes with 5-chloro-8-(methoxycarbonylme- thoxy)quinoline ligand (L), namely, HgLBr2 1 and CuL2Cl2 2, have been prepared by solvothermal reaction of (5-chloro-quinolin-8-yloxy)acetic acid with HgBr2 and CuCl2, respectively. Their structures were characterized by IR, elemental analysis, UV-Vis-NIR spectra, TG and single-crystal X-ray diffraction analysis. Interestingly, (5-chloro-quinolin-8-yloxy)acetic acid is changed as 5-chloro-8-(methoxycarbonylmethoxy)quinoline ligand (L) in complexes 1 and 2. Crystal data for 1: C12H10Br2ClHgNO3, Mr = 612.07, triclinic, space group P with a = 8.5983(7), b = 9.7726(6), c = 10.1549(6) Å, α = 66.355(6), β = 77.067(8), γ = 78.803(8)°, V = 756.6(9) Å3, Z = 2, Dc = 2.687 g/cm3, F(000) = 560, μ = 15.633 mm-1, R = 0.0351 and wR = 0.0504. Crystal data for 2: C24H20Cl4CuN2O6, Mr = 637.76, triclinic, space group P with a = 10.5324(9), b = 11.2377(16), c = 12.0143(12) Å, α = 83.413(11), β = 64.475(9), γ = 83.144(11)°, V = 1270.9(2) Å3, Z = 2, Dc = 1.667 g/cm3, F(000) = 646, μ = 1.324 mm-1, R = 0.0408 and wR = 0.0922. In 1, the HgII centre is a distorted trigonal planar geometry comprised of two Br atoms and one quinoline N atom of L. Intermolecular π-π, C–H•••π stacking interactions and intermolecular C–H•••Br hydrogen bonds are observed in the molecular packing of 1. In complex 2, each CuII center has a distorted octahedral geometry comprised of two chloride ions, two quinoline N atoms and two O atoms of two L ligands. Intermolecular C–H•••Cl hydrogen bonds exist in the molecular packing of 2. The fluorescence emission peak of complexes 1 and 2 appears near 406 and 410 nm, respectively. Optical diffuse-reflection spectral results suggest complex 1 has the property of semiconductor.
