| 摘 要： | Using the deep eutectic solvent formed of oxalic acid and choline chloride, a new charge-assisted hydrogen-bonded host framework [Co(en)3]2[Zr2(C2O4)7]·2H2O(1) has been obtained. The title complex crystallizes in the monoclinic, space group P21/n(No. 14) with a = 7.7448(10), b = 14.5683(19), c = 19.375(3), β = 92.124(2)o, V = 2184.5(5) 3, Z = 4, Dc = 1.996 g.cm-3, F(000) = 1332, μ = 1.328 mm-1, R = 0.0353 and w R = 0.0718(Ⅰ 2σ(Ⅰ)). Single-crystal structure analysis reveals that the title complex possesses a 3D network assembled through a multitude of charge-assisted hydrogen bonds between the in situ generated anionic coordination complexes [Zr2(C2O4)7]6- and metal complexes Co(en)33+.
