Three polymeric complexes containing polynuclear CoII units, [Co2(Cbtp)2(ip)2] (1), [N(CH3) 4]2[Co3(ip)4] (2), and [{Co 7(ip)5(μ-OH)4}(μ-bpp)2] ·2(H2O) (3), have been prepared by solvothermal synthesis. Isophthalic acid (H2ip) has been used for the construction of polynuclear CoII 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 CoII compounds: 1-D structure containing dinuclear CoII units with Cbtp, 2-D structure containing trinuclear CoII units without quinazoline, and 3-D structure containing heptanuclear CoII units with bpp. The gas sorption study of 3 revealed a relative high uptake of CO2 over N2 because of small dimension of channels. The thermal stabilities and magnetic properties of these complexes were also examined.
