Abstract
The crystal structure of the title compound, [Ni-2(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 centr osymmetrically related Ni II atoms. The distorted octahedral environment of each Ni-II atom is completed by the three N atoms of the diethylenetriamin e ligand in a fac arrangement and one water O atom. Variable-temperature ma gnetic susceptibility measurements reveal a moderate intramolecular antifer romagnetic coupling.
