C. Guzmán-Miralles, O. Castillo, A. Luque, J. I. Beitia and P. Román

Abstract: The crystal structure of the title compound, [Ni₂(C₂O₄)(C₄H₁₃N₃)₂(H₂O)₂](NO₃)₂, consists of uncoordinated nitrate anions and dimeric cations, where the oxalate ligand is coordinated in a bis-bidentate fashion to centrosymmetrically related Ni^II atoms. The distorted octahedral environment of each Ni^II atom is completed by the three N atoms of the diethylenetriamine ligand in a fac arrangement and one water O atom. Variable-temperature magnetic susceptibility measurements reveal a moderate intramolecular antiferromagnetic coupling.
