Dibromidobis(pyridine-3-carbonitrile-?N)zinc(II).

ABSTRACT: In the title compound, [ZnBr(2)(C(6)H(4)N(2))(2)], the Zn(II) atom is four coordinated in a slightly distorted tetra-hedral fashion by two pyridine N atoms and two Br(-) anions. ?-? inter-actions between adjacent pyridine rings [centroid-centroid distance = 3.6229?(19)?Å] are the main factor controlling the packing and are effective in the stabilization of the crystal structure.

trans-Dibromidobis(3-methyl-pyridine-?N)copper(II).

Project description:The asymmetric unit of the title compound, [CuBr(2)(C(6)H(7)N)(2)], contains one half-mol-ecule, the whole mol-ecule being generated by inversion through a center located at the Cu(II) atom. The geometry around the Cu(II) atom is square planar. Semicoordinate Cu?Br bonds [3.269?(1)?Å] and nonclassical C-H?Br hydrogen bonds connect the mol-ecules, forming chains running parallel to the a axis. These chains are further linked via additional C-H?Br hydrogen bonds into a three-dimensional network.

cis-Dibromidobis(2-phenyl-pyridine-?N)platinum(II).

Project description:In the title complex, [PtBr(2)(C(11)H(9)N)(2)], the Pt(II) ion has a distorted cis-Br(2)N(2) square-planar coordination geometry defined by two N atoms from two 2-phenyl-pyridine (ppy) ligands and two Br(-) anions. The ppy ligands are not planar, the dihedral angles between the pyridine and benzene rings being 49.0?(3) and 47.3?(3)°. In the crystal, the complex mol-ecules are stacked in columns along the a axis. In the columns, there are numerous intra- and inter-molecular ?-? inter-actions between the six-membered rings, the shortest ring centroid-centroid distance being 3.774?(6)?Å.

Dibromidobis(1-ethyl-2,6-dimethyl-pyridinium-4-olate-?O)zinc(II).

Project description:In the bioactive title compound, [ZnBr(2)(C(9)H(13)NO)(2)], the Zn(II) atom is coordinated in a distorted tetra-hedral arrangement by two Br(-) anions and the O atoms of two zwitterionic organic ligands. The pyridinium rings are almost planar [maximum deviations = 0.004?(4) and 0.003?(4)?Å]. The ethyl groups are approximately perpendicular to the corresponding pyridinium ring planes [N-C-C-C = 88.8?(4)° in each ligand]. The packing of the mol-ecules is controlled by ?-? inter-actions, with centroid-centroid distances of 3.625?(3) and 3.711?(2)?Å, forming chains approximately parallel to (102). The crystal studied was non-merohedrally twinned (twin relationship between the domains 1 0 0, 0 1 0, -0.4672 -0.1864 -1 and batch scale factor of 7.39%).

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

Project description: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.

Oxalic acid-pyridine-4-carbonitrile (1/2).

Project description:In the title compound, 2C(6)H(4)N(2)·C(2)H(2)O(4), the oxalic acid mol-ecule lies about an inversion center. The pyridine ring of the pyridine-4-carbonitrile mol-ecule is almost planar, the largest deviation from the least-squares plane being 0.006?(1)?Å; the nitrile N atom deviates from this plane by 0.114?(1)?Å. In the crystal, the oxalic acid mol-ecules and the pyridine-4-carbonitrile mol-ecules form stacks. Neighboring mol-ecules within the stacks are related by translation in the a direction, with inter-planar distances of 3.183?(1) and 3.331?(2)?Å, respectively. Each oxalic acid mol-ecule forms strong O-H?N hydrogen bonds with two mol-ecules of pyridine-4-carbonitrile. Besides this, there are also weak C-H?O inter-actions.
