摘要：

The crystal structure of the title compound, [Cu-2(C2O4)(2)(C2H3N3)(2)(H2O)(4)], consists of dimeric neutral entities with D-2 (222) point symmetry. The two Cu-II atoms (site symmetry 2) are linked by two symmetry-related N-1,N-2-bidentate 1,2,4-triazole bridges (one of the N atoms has site symmetry 2). The distorted octahedral coordination around each Cu atom is completed by two O donor atoms from a terminal bidentate oxalate ligand in the equatorial plane, and two trans-coordinated water molecules occupying the apical positions with longer metal-oxygen distances. The complete solid-state structure can be described as a three-dimensional supramolecular framework, stabilized by extensive hydrogen-bonding interactions involving the water molecules, the noncoordinated oxalate O atoms and the protonated N atom of the triazole ligands. The thermal degradation of the title compound was carried out in air between 298 and 873 K.
