摘要
The cobalt（II） complex with （quinolin-8-yloxy）acetate, [CoCl（C11H8NO3）]n （1）, has been prepared via the solvothermal method and characterized by IR, elemental analysis, UV- Vis diffuse-reflection spectra and single-crystal X-ray diffraction analysis. Complex 1 is a novel carboxylate-bridged one-dimensional helical cobalt（II） polymer, and the Co（II） centre exhibits an approximately square pyramidal CoClNO3 coordination geometry. It crystallizes in monoclinic, space group P21/n, with a = 9.1594（10）, b = 6.8864（7）, c = 17.290（2） , β = 102.629（3）o, C11H8ClCoNO3, Mr = 296.56, V = 1064.2（2） 3, Z = 4, Dc = 1.851 g/cm3, F（000） = 596, μ = 1.856 mm-1, the final R = 0.0308 and wR = 0.0807. Interestingly, the chain complexes are assembled to form two-dimensional networks through intermolecular face-to-face π-π stacking interactions with the centroid-to-centroid distance of 3.559（1） and the dihedral angle of 8.4（1）° between the aromatic rings.
