摘要
Two new organic supramolecular cocrystal complexes C18H18O4·C10H8N2（I） and C18H18O4·C12H10N2（II）（C18H18O4 = 2,3,6,7-tetrahydroxyl-9,10-dimethyl-9,10-dihydro-9,10-ethanoanthracene（LH4）, C10H8N2 = 4,4＇-bipyridine（bpy） and C12H10N2 = 4,4＇-bipyridinylethane（bpe）） have been obtained by mixing LH4 with corresponding bpy or bpe ligand. The two complexes have been determined by X-ray crystal structure analysis, elemental analysis and IR analysis. Compound I crystallizes in the orthorhombic Pnma with a = 9.7078（4）, b = 22.4974（10）, c = 20.6272（9） V = 4505.0（3）3, Mr = 454.51, Dc. = 1.340 g·cm^-3, μ = 0.09 mm-1, F（000） = 1920, Z = 8, R = 0.0503 and wR = 0.1360. Compound II crystallizes in monoclinic C2/c with a = 29.944（6）, b = 9.820（2）, c = 22.643（5） , V = 5048.4（18）3, Mr = 480.54, Dc. = 1.265 g cm^–3, μ = 0.084 mm^–1, F（000） = 2032, Z = 8, R = 0.0548 and wR = 0.1600. X-ray single-crystal structure analysis shows that two-dimensional（2D） layer supramolecular structures are formed through hydrogen bonds and π-π interactions in the two complexes. IR analysis also indicates that there are only associated hydroxyl groups in the two complexes.
