Abstract: The copper(II) complex, [Cu(C4H10N4O)2](NO3)2 or [Cu(L1e)2](NO3)2, where L1e is 1-carbamimidoyl-2-ethylisourea, was obtained from a 1:2 molar ratio of copper(II) nitrate hemipentahydrate with 2-cyanoguanidine in ethanol. The crystal structure consists of the centrosymmetric [Cu(L1e)2]2+ cation and two NO3- counter-anions. The cation exhibits four-coordinate bonding of the two N,N-bidentate ligands and the CuII atom through the N-donor atoms, yielding a square-planar CuN4 geometry. Intermolecular N-H
O hydrogen bonds link between the cation and and counter-anion, forming a two-dimentional layered structure extending parallel to (
01).
