A new 3D cobalt metal-organic framework [C_7H_(13)N_2]_2[(CH_3COO)_2Co_7(oba)_5-(Hoba)_2(OH)_2]·H_2O has been synthesized under ionothermal conditions and characterized by elemental analysis, FT-IR, XRD, and TG. This complex crystallizes in monoclinic system, space group P21/c with a = 19.4499(4), b = 10.8839(2), c = 27.7796(5) ?, β = 104.467(2)o, V = 5694.22(19) ?~3, Z = 2, C_(116)H_(92)Co_7N_4O_(42), M_r = 2626.45, D_c = 1.532 g/cm~3 , F(000) = 2682, μ = 1.085 mm-1, R = 0.0387 and wR = 0.1177. Its structure is characterized as a 3D open framework constructed by seven nuclear clusters [(CH_3COO)_Co_7(OH)_2] and the 4,4?-oxybisbenzoic acid ligand. The used ILs cations are located in the middle of the pore and compensate for the negative charges of framework. Furthermore, its fluorescence property has also been studied.
