摘要A new binuclear cobalt(II) complex, [Co2(C10H6NO2)2(C12H8N2)2(N3)2]·H2O (1, C10H6NO2-: isoquinoline-1-carboxylate, C12H8N2: 1,10-phenanthroline (phen); N3-: azide), has been synthesized though a mixed-solvothermal method using the pentanol and distilled water as solvent. The complex was characterized by elemental analysis, IR spectrum and single-crystal X-ray diffraction. It crystallizes in triclinic system, space group P with Z = 2, a = 1.777(5), b = 11.815(5), c = 17.141(7) Å, α = 74.496(6)°, β = 70.537(6)°, γ = 67.861(6)°, V = 2055.4(14) Å3, Mr = 922.66, Dc = 1.491 g/cm3, λ = 0.71073 Å, μ = 0.870 mm-1, F(000) = 942, R = 0.0455 and wR = 0.1147 for 4960 observed reflections with I > 2σ(I) and S = 1.129. Its molecular structure is constructed by two Co2+ cations, two chelating phen ligands, two chelating isoquinoline-1-carboxylate ligands, two bridging linear azide anions and two uncoordinated half-occupied water molecules. The 3-D supramolecular network results from the multiple hydrogen bonds and π-π stacking interactions among three types of ligands.

The complex was characterized by elemental analysis, IR spectrum and single-crystal X-ray diffraction. It crystallizes in triclinic system, space group P with Z = 2, a = 1.777(5), b = 11.815(5), c = 17.141(7) Å, α = 74.496(6)°, β = 70.537(6)°, γ = 67.861(6)°, V = 2055.4(14) Å3, Mr = 922.66, Dc = 1.491 g/cm3, λ = 0.71073 Å, μ = 0.870 mm-1, F(000) = 942, R = 0.0455 and wR = 0.1147 for 4960 observed reflections with I > 2σ(I) and S = 1.129.
