Dibromidobis-(4-hydr-oxy-1,5-dimethyl-2-phenyl-3-pyrazolone)zinc(II).

ABSTRACT: In the title compound, [ZnBr(2)(C(11)H(12)N(2)O(2))(2)], the Zn(II) ion is coordinated by two Br atoms and two O atoms from two 4-hydroxy-anti-pyrine mol-ecules via the carbonyl O atoms, which act as monodentate ligands, giving rise to a distorted tetra-hedral geometry. The values of the bond angles at the Zn atom are in the range 99.4?(1) to 113.2?(1)°. The presence of O-H?O and O-H?Br intra-molecular hydrogen bonds can explain the difference between the two Zn-O [1.961?(3)/2.015?(3)?Å] and the two Zn-Br [2.350?(1)/2.378?(1)?Å] bond lengths. The crystal structure is governed by C-H?O, C-H?Br and Zn-Br?Cg(?-ring) inter-actions.

Project description:The title compound, C(15)H(14)O(2), was obtained by Friedel-Crafts acyl-ation between 2,5-dimethyl-phenol and benzoyl chloride in the presence of aluminium chloride as a catalyst.

catena-Poly[[bis-(2-hydr-oxy-2-phenyl-acetato-κO,O)zinc(II)]-μ-1,2-di-4-pyridylethane-κN:N'].

Project description:The title compound, [Zn(C(8)H(6)O(3))(2)(C(12)H(12)N(2))](n), consists of [Zn(Hopa)(2)] (H(2)opa = 2-hydr-oxy-2-phenyl-acetic acid or mandelic acid) units bridged by 1,2-di-4-pyridylethane (bpe) ligands, forming a polymeric chain developing parallel to the b axis. The bridging bpe ligand is arranged around a twofold axis passing through the middle of the ethane C-C bond. The geometry around the Zn(II) ion is distorted octa-hedral, constructed by four O atoms from two Hopa(-) ligands and two N atoms from two bridging bpe ligands. O-H⋯O hydrogen bonds link the chains, forming a three-dimensional network.

Project description:The title compound, C(19)H(19)N(3)O(2), is a Schiff base compound derived from 4-amino-anti-pyrine and 5-hydr-oxy-2-methyl-benzaldehyde. The mol-ecule adopts a trans configuration about the central C=N bond. There is an intra-molecular O-H?N hydrogen bond. Futhermore, weak C-H?O hydrogen bonds lead to the formation of a chain developing parallel to the b axis.

Project description:In the title mol-ecule, C(16)H(16)N(2)O(3), intra-molecular O-H?O hydrogen bonds influence the mol-ecular conformation. Inter-molecular O-H?O hydrogen bonds [O?O = 2.922?(2)?Å] link the mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H?O inter-actions assemble these dimers into layers parallel to the bc plane.

Aqua-bis(3'-hydr-oxy-2,2'-bipyridine-3-olato-?N,N')zinc(II).

Project description:In the title complex, [Zn(C(10)H(7)N(2)O(2))(2)(H(2)O)], the Zn(II) ion and water O atom are located on a crystallographic twofold rotation axis and the metal atom assumes a distorted trigonal-bipyramidal ZnN(4)O coordination geometry. An intra-molecular O-H?O hydrogen bond occurs within the ligand and inter-molecular O-H?O hydrogen bonds involving the water mol-ecule result in a sheet structure in the crystal structure. In addition, a short C-O?? contact between the O atom of the deprotonated hydroxyl group and a nearby pyridine ring [O?Cg = 3.977?(2)?Å, where Cg is the centroid of the pyridine ring] is observed.

Aqua-(2-hydr-oxy-5-sulfonatobenzoato-?O)bis-(2-phenyl-1H-1,3,7,8-tetra-aza-cyclo-penta-[l]phenanthrene-?N,N)zinc(II).

Project description:In the title compound, [Zn(C(7)H(4)O(6)S)(C(19)H(12)N(4))(2)(H(2)O)], the Zn(II) ion is coordinated by two N,N'-bidentate 2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene ligands, one O-monodentate 5-sulfosalicylate dianion and a water mol-ecule. This results in a distorted cis-ZnO(2)N(4) octa-hedral coordination geometry for the metal ion. In the crystal, mol-ecules are expanded into a three-dimensional supra-molecular motif via O-H?O, O-H?N and N-H?(O,S) hydrogen bonds. In addition, ?-? stacking inter-actions between the aromatic rings of the polycyclic ligands consolidate the sturcture [shortest centroid-centroid distance = 3.501?(2)?Å].
