The asymmetric unit of the title co-crystal, 2CH(4)N(2)O·C(6)H(10)O(4), contains two urea mol-ecules and two half-mol-ecules of adipic acid; the latter are completed by crystallographic inversion symmetry. The crystal packing is stabilized by O-H⋯O and N-H⋯O hydrogen bonds, generating a chain along [110]. Additional weak inter-chain O-H⋯O and N-H⋯O inter-molecular inter-actions lead to the formation of a three-dimensional network.
标题共晶体2CH₄N₂O·C₆H₁₀O₄的不对称单元包含两个尿素分子和两个己二酸半分子；后者通过晶体学倒转对称性形成完整分子。晶体堆积通过O—H⋯O和N—H⋯O氢键得以稳定，沿[110]方向形成一条链。额外的弱链间O—H⋯O和N—H⋯O分子间相互作用导致形成三维网络。
