ABSTRACT: In the title compound, [ZnI(2)(C(12)H(9)BrN(2))], the metal centre displays a moderately distorted tetra-hedral coordination geometry defined by two iodide anions and two N atoms of the organic ligand. The dihedral angle between the pyridine and benzene rings is 15.15 (13)°.
Project description:In the title compound, [CrCl(3)(C(19)H(13)Br(2)N(3))], the Cr(3+ )ion is coordinated by the tridentate 2,6-bis-[(4-bromo-phen-yl)imino-meth-yl]pyridine Schiff base ligand in a fac-octa-hedral geometry. The dihedral angles between the pyridine and benzene rings are 23.9 (6) and 70.7 (1)°.
Project description:In the title compound, [ZnBr(2)(C(12)H(9)N(3)O(2))], the Zn(II) ion is bonded to two Br ions and two N atoms of the diimine ligand in a distorted tetra-hedral geometry. With the exception of the Br atoms, all other atoms are disordered over two sets of sites corresponding to a 180° rotation of the mol-ecule along [[Formula: see text]02]. The refined occupancies of the components are 0.809 (2) and 0.191 (2). In addition, the crystal studied was a non-merohedral twin with a refined component ratio of 0.343 (2):0.657 (2).
Project description:The Cu(II) atom in the title complex, [CuCl(2)(C(12)H(9)IN(2))], has a square-planar coordination being N,N'-chelated by the Schiff base ligand, and by two Cl atoms. The geometry is distorted towards square pyramidal owing to a long Cu⋯Cl inter-action of 2.941 (1) Å. This results in the formation of a zigzag chain structure propagating in the c-axis direction.
Project description:In the title complex, [CuCl(2)(C(14)H(14)N(2))], the Cu(II) atom exhibits a very distorted tetra-hedral coordination geometry involving two chloride ions and two N-atom donors from the Schiff base ligand. The range for the six bond angles about the Cu(2+) cation is 81.49 (11)-145.95 (9)°. The chelate ring including the Cu(II) atom is approximately planar, with a maximum deviation of 0.039 (4) Å for one of the C atoms; this plane forms a dihedral angle of 46.69 (9)° with the CuCl(2) plane.
Project description:In the title complex, [ZnBr(2)(C(12)H(9)BrN(2))], the Zn(II) ion is in a distorted tetra-hedral coordination environment formed by two imine N atoms of the bis-chelating N-heterocyclic ligand and two Br atoms. The dihedral angle between the pyridine and benzene rings is 8.04?(17)°.
Project description:In the crystal structure of the title compound, [Cu(C(12)H(9)BrN(2))(2)](C(24)H(20)B), the copper(I) cation is coordinated by four N atoms of two crystallographically independent 2-[(4-bromo-phen-yl)imino-meth-yl]pyridine ligands within a distorted tetra-hedron.
Project description:In the mol-ecule of the title compound, [ZnI(2)(C(14)H(14)N(2))], the Zn atom is four-coordinated in a distorted tetra-hedral geometry by two N atoms of the Schiff base ligand and by two I atoms. The benzene and pyridine rings are oriented at a dihedral angle of 70.75?(3)°. The five-membered ring has an envelope conformation. There is a weak ?-? inter-action between benzene rings, with a centroid-to-centroid distance of 3.975?(4)?Å.
Project description:The unique Hg(II) ion in the title centrosymmetric dinuclear complex, [Hg(2)Cl(4)(C(12)H(9)BrN(2))(2)], is in a distorted trigonal-bipyramidal coordination environment formed by the bis-chelating N-heterocyclic ligand, two bridging Cl atoms and one terminal Cl atom. One of the bridging Hg-Cl bonds is significantly longer than the other.
Project description:The binuclear title complex, [Cu(2)Cl(4)(C(14)H(14)N(2))(2)], is located on a crystallographic inversion centre. The Cu(II) ion is in a distorted square-pyramid coordination environment formed by the bichelating N-heterocyclic ligand, two bridging Cl atoms and one terminal Cl atom. One of the bridging Cu-Cl bonds is significantly longer than the other.
Project description:In the title complex, [ZnI(2)(C(14)H(21)BrN(2)O)]·CH(3)OH, the asymmetric unit consists of a mononuclear zinc(II) complex mol-ecule and a methanol solvent mol-ecule. The compound was derived from the zwitterionic form of the Schiff base 4-bromo-2-[3-(diethyl-amino)propyl-imino-meth-yl]phenol. The Zn(II) atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand and by two iodide ions in a distorted tetra-hedral coordination. In the crystal structure, the methanol mol-ecules are linked to the Schiff base mol-ecules through N-H?O and O-H?O hydrogen bonds. One I atom is disordered over two positions in a 0.702?(19):0.298?(19) ratio.
