摘要

Three polymeric complexes containing polynuclear Co~(II) units, [Co_2(Cbtp)_2(ip)_2] (1), [N(CH_3) _4]_2[Co_3(ip)_4] (2), and [{Co _7(ip)_5(μ-OH)_4}(μ-bpp)_2] ·2(H_2O) (3), have been prepared by solvothermal synthesis. Isophthalic acid (H_2ip) has been used for the construction of polynuclear Co~(II) units, and three auxiliary ligands, namely Cbtp, quinazoline, and bpp, have also been employed to change nuclearity of Co ~(II) unit and the dimensionality of polymeric Co~(II) compounds: 1-D structure containing dinuclear Co~(II) units with Cbtp, 2-D structure containing trinuclear Co~(II) units without quinazoline, and 3-D structure containing heptanuclear Co~(II) units with bpp. The gas sorption study of 3 revealed a relative high uptake of CO_2 over N_2 because of small dimension of channels. The thermal stabilities and magnetic properties of these complexes were also examined.
