The crystal structure is stabilized by CÐHÁ Á ÁO and CÐHÁ Á ÁN intra-and intermolecular hydrogen bonds. Comment

The title compound, C10H11ClN4O, displays the characteristic features of 1,2,4‐triazole derivatives. The crystal structure is stabilized by N—H⋯O intermolecular hydrogen bonds.

The title mol­ecule, [Cu2(H2N2O2)4(H2O)2], possesses a center of symmetry and contains two almost planar eight‐membered central rings which are nearly normal to each other. Molecules are linked by O—H⋯O hydrogen bonds to form a three‐dimensional network.
