Abstract: The title complex, [Cu(C₄H₁₀N₄O)₂](ClO₄)₂ or [Cu(L^1e)₂](ClO₄)₂, where L^1e is 1-carbamimidoyl-2-ethylisourea, was obtained from the ethanolysis reaction of 2-cyanoguanidine and copper(II) perchlorate hexahydrate in a 2:1 molar ratio. The two bidentate L^1e ligands are coordinated to the Cu^II center through N-donor atoms, leading to the CuN₄ chromophore. The Cu^II environment is slightly distorted square-planar, with a dihedral angle of 5.17 (6)° between the two six-membered chelate rings. One of the ClO₄^- anions is disordered over two positions in a 0.6:0.4 ratio.
