Synthesis and characterization of a novel one-dimensional metal organic compound

A novel metal organic compound of Zn²⁺ coordinated with 4,5-diazafluorene-9-one-N₂ (C₂₂H₁₂N ₆) has been synthesized under solvothermal condition. Single-crystal X-ray diffraction analysis showed that the compound is a one-dimensional zig-zag chain structure combined by Cl⋯H-C bonds. The crystal is of orthorhombic, space group Pnna, C₂₂H₁₂N₆Cl ₂Zn, M_r = 496.65, a = 8.1132(13), b = 18.983(3), c = 13.116(2) Å, Z = 4, V = 2020.2(5) ų, D_c = 1.633 g/cm³, μ = 1.504 mm^-1, F(000) = 1000, T = 293(2) K, the final R = 0.0626 and wR = 0.1474 for 2390 unique reflections and 150 parameters with I > 2σ(I). The refinement method was full-matrix least-squares on F² with GOF = 0.951. This compound was also characterized by FT-IR, Raman, UV-vis spectra, and TG-DTA.
