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)Å, β=92.124(2)°, V=2184.5(5)Å³, Z=4, D_c=1.996 g·cm^-3, F(000)=1332, μ=1.328 mm^-1, R=0.0353 and wR=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⁺.
