Bis{2-bromo-4-chloro-6-[2-(phenyl-sulfon-yl)hydrazonometh-yl]phenolato-κN,O}copper(II).

ABSTRACT: The Cu atom in the title compound, [Cu(C(13)H(9)BrClN(2)O(3)S)(2)], is chelated by two deprotonated Schiff base ligands in a square-planar coordination geometry; the Cu atom lies on a center of inversion. The -NH- group of one anion forms an intra-molecular hydrogen bond to the phenolate atom of the symmetry-related ion.

Bis{(E)-4-bromo-2-[(2-chloro-3-pyrid-yl)imino-meth-yl]phenolato-?N,O}copper(II).

Project description:In the title complex, [Cu(C(12)H(7)BrClN(2)O)(2)], the Cu(II) center is tetra-coordinated by two phenolate O and two azomethine N atoms from two independent bidentate 4-bromo-2-[(2-chloro-3-pyrid-yl)imino-meth-yl]phenolate (L) ligands. In the crystal structure, the Cu(II) atom has a distorted square-planar coordination environment. The inter-planar dihedral angles between the benzene and pyridine rings in the individual ligands are 63.83?(4) and 54.43?(3)°, indicating the pyridine ring to have considerably weaker steric hindrance.

Bis{6-bromo-4-chloro-2-[(E)-(2-chloro-phenyl)-imino-meth-yl]-phenolato-?(2)N,O}copper(II).

Project description:In the title compound, [Cu(C(13)H(7)BrCl(2)NO)(2)], or CuL(2) {where HL= 2-[(E)-(2-chloro-phenyl-imino)-meth-yl]-6-bromo-4-chloro-phenol}, the Cu(II) atom is located on an inversion center and has a square-planar coordination. In the crystal, complex mol-ecules are linked via Cu?Cl inter-actions [2.9933?(11)?Å], forming a two-dimensional network parallel to the bc plane. They are also Cl?Cl inter-actions [3.3709?(14)?Å] present, which consolidate the two-dimensional network structure.

Chlorido{4-chloro-2-[(2-morpholinoeth-yl)imino-meth-yl]phenolato-κN,N',O}copper(II).

Project description:The Cu(II) atom in the title compound, [Cu(C(13)H(16)ClN(2)O(2))Cl], exists in a distorted square-planar coordination environment as the deprotonated Schiff base chelates to the Cu(II) atom through three atom sites. In the crystal structure, adjacent mol-ecules are linked by a Cu⋯Cl [3.011 (1) Å] bridge, generating a linear chain running along the b axis of the ortho-rhom-bic unit cell.

Bis{4-bromo-2-[(naphthalen-1-yl-imino)-meth-yl]phenolato-?N,O}copper(II).

Project description:The title complex, [Cu(C(17)H(11)BrNO)(2)], lies on a centre of inversion. The chelating Schiff base anions define a square-planar N(2)O(2) donor set. The nearly perpendicular orientation of the naphthyl residues of the chelate ring [dihedral angle = 82.12?(12)°] precludes the Cu(II) centre from additional coordination. In the refinement, the naphthyl rings were found to be disordered over two positions.; the major component has a site occupancy of 0.667?(4).

N,N'-Bis(4-chloro-phenyl-sulfon-yl)suberamide.

Project description:The asymmetric unit of the title compound, C(20)H(22)Cl(2)N(2)O(6)S(2), contains one half-mol-ecule with a center of symmetry at the mid-point of the central C-C bond.

In the crystal, inter-molecular N-H?O(C) and N-H?O(S) hydrogen bonds link the mol-ecules into chains along the b axis.
