چکیده
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) environment is slightly distorted square-planar, with a dihedral angle of 5.17 (6)° between the two six-membered chelate rings. One of the ClO(4) (-) anions is disordered over two positions in a 0.6:0.4 ratio.

Each Cu atom in the dinuclear centrosymmetric title complex, [Cu(2)Br(2)(C(14)H(17)N(3))(2)](ClO(4))(2), is ligated in a distorted square-pyramidal geometry (τ = 0.31) by a tridentate bis-[2-(2-pyrid-yl)eth-yl]amine ligand, and by two bridging Br atoms. In addition, the dinuclear species is stabilized by two hydrogen-bonded perchlorate anions.

The title dinuclear copper complex, [Cu(2)(C(15)H(15)N(6)O)Cl(2)(CH(3)OH)(2)]ClO(4), was prepared by the reaction of copper(II) chloride with bis-[1-(2-pyrid-yl)ethyl-idene]carbonohydrazide in the presence of sodium perchlorate in a methanol solution. It features a mono-deprotonated bis-tridentate ligand, which coordinates to two independent Cu(II) ions, one of which is coordinated by pyridyl N...

In the title compound, {[Cu(C10H8N4)3(H2O)2](ClO4)2} n , the coordination environment of the cationic Cu(II) atom is distorted octa-hedral, formed by pairs of symmetry-equivalent 1,2-bis-(pyridin-4-yl)diazene ligands, bridging 1,2-bis-(pyridin-4-yl)diazene ligands and two non-equivalent water mol-ecules. The 1,2-bis-(pyridin-4-yl)diazene mol-ecules form polymeric chains parallel to [-101] via a...

In the title complex, [Cu(ClO(4))(2)(C(7)H(12)N(2)O)(2)], the Cu(II) ion lies on a crystallographic inversion centre. The coordination sphere around Cu(II) ion can be described as tetragonally distorted octa-hedral with two perchlorate O atoms occupying the apical positions and four N atoms from two N(1)-(2-furyl-methyl)ethane-1,2-diamine ligands in the basal plane.
