Bis(1-carbamimidoyl-2-ethylisourea)copper(II) dinitrate
نویسندگان
چکیده
The copper(II) complex, [Cu(C(4)H(10)N(4)O)(2)](NO(3))(2) or [Cu(L(1e))(2)](NO(3))(2), where L(1e) is 1-carbamimidoyl-2-ethyl-isourea, was obtained from a 1:2 molar ratio of copper(II) nitrate hemipenta-hydrate with 2-cyano-guanidine in ethanol. The crystal structure consists of the centrosymmetric [Cu(L(1e))(2)](2+) cation and two NO(3) (-) counter-anions. The cation exhibits four-coordinate bonding of the two N,N-bidentate ligands and the Cu(II) atom through the N-donor atoms, yielding a square-planar CuN(4) geometry. Inter-molecular N-H⋯O hydrogen bonds link between the cation and and counter-anion, forming a two-dimentional layered structure extending parallel to (01).

The title complex, [Cu(C(4)H(10)N(4)O)(2)](ClO(4))(2) or [Cu(L(1e))(2)](ClO(4))(2), where L(1e) is 1-carbamimidoyl-2-ethyl-isourea, was obtained from the ethano-lysis reaction of 2-cyano-guanidine and copper(II) perchlorate hexa-hydrate 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 CuN(4) chromophore. The Cu(II) ...
