Crystal structure and thermodecomposition kinetics of a three-dimensional supramolecular Mn complex with 8-hydroxyquinoline

A three-dimensional supramolecular complex, Mn(8-OHQ)₃] · CH₃OH (8-OHQ is 8-hydroxyquinoline), C₂₈H₂₂MnN₃O₄, was synthesized in methanol, and its crystal structure was determined by X-ray crystallography. The crystals are triclinic, space group P $P\bar 1$ , a = 10.823(2) Å, b = 13.222(3) Å, c = 17.283(3) Å, α = 90.03(3)°, β = 93.15(3)°, γ = 92.58(3)°, V = 2467.0(8) ų, Z = 4, F(000) = 1072, ρ = 1.399 g/cm³, μ = 0.575 mm^?1. Hydrogen bonds and intermolecular interactions, which are observed in the complex, stabilize its structure. The thermal decomposition kinetics of the complex was investigated under nonisothermal conditions using the Achar differential method and the Coats-Redfern integral method.
