Crystal structure of bis­­{μ2-3-(pyridin-2-yl)-5-[(1,2,4-triazol-1-yl)meth­yl]-1,2,4-triazolato}bis­­[aqua­nitrato­copper(II)] dihydrate

The structure of the dinuclear title complex, [Cu2(C10H8N7)2(NO3)2(H2O)2]·2H2O, consists of centrosymmetric dimeric units with a copper–copper separation of 4.0408 (3) Å. The CuII ions in the dimer display a distorted octa­hedral coordination geometry and are bridged by two triazole rings, forming an approximately planar Cu2N4 core (r.m.s. deviation = 0.049 Å). In the crystal, O—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds and π–π inter­actions link the mol­ecules into a three-dimensional network.
