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

ABSTRACT: 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%).

Bis(2,6-dimethyl-pyridinium) tetra-bromido-zincate(II).

Project description:In the crystal structure of the title compound, (C(7)H(10)N)(2)[ZnBr(4)], the coordination geometry of the anion is approximately tetra-hedral and a twofold rotation axis passes through the Zn atom. The Zn-Br bond lengths range from 2.400?(2) to 2.408?(3)?Å and the Br-Zn-Br angles range from 108.14?(6) to 115.15?(15)°. In the crystal structure, the [ZnBr(4)](2-) anion is connected to two cations through N-H?Br and H(2)C-H?Br hydrogen bonds, forming two-dimensional cation-anion-cation layers normal to the b axis. No significant Br?Br inter-actions [the shortest being 4.423?(4)?Å] are observed in the structure.

2,6-Dimethyl-pyridinium bromide.

Project description:The asymmetric unit of the title salt, C(7)H(10)N(+)·Br(-), comprises two 2,6-dimethyl-pyridinium cations and two bromide anions. One cation and one anion are situated in general positions, while the other cation and the other anion lie on a crystallographic mirror plane parallel to (010). Each pair of ions inter-act via N-H?Br and C-H?Br hydrogen bonding, generating motifs depending on the cation and anion involved. Thus, the cation and the anion on the mirror plane generate infinite chains along the c axis, while the other ionic pair leads to sheets parallel to the ac plane. In the overall crystal packing, both motifs alternate along the b axis, with a single layer of the chain motif sandwiched between two double layers of the sheet motif. The sheets and chains are further connected via aryl ?-? inter-actions [centroid-centroid distances = 3.690?(2) and 3.714?(2)?Å], giving a three-dimensional network.

Bis(2,6-dimethyl-pyridinium) tetra-bromido-cobaltate(II).

Project description:In the crystal structure of the title compound, (C(7)H(10)N)(2)[CoBr(4)], the [CoBr(4)](2-) anion is connected to two cations through N-H?Br and H(2)C-H?Br hydrogen bonds to form two-dimensional cation-anion-cation layers normal to the crystallographic b axis. Inter-actions of the ?-? type are absent between cations in the stacks [centroid-centroid separation = 5.01?(5)?Å]. Significant inter-molecular Br-aryl inter-actions are present in the structure, especially an unusually short Br-ring centroid inter-action of 3.78?(1)?Å. The coordination geometry of the anion is approximately tetrahedral and a twofold rotation axis passes through the Co atom.

Poly[bis-(μ-2,6-dimethyl-pyridinium-3,5-dicarboxyl-ato-κO:O)copper(II)].

Project description:In the title coordination polymer, [Cu(C(9)H(8)NO(4))(2)](n), the Cu atom, located on a twofold rotation axis, is four coordinate in a distorted square-planar environment. Each 2,6-dimethyl-pyridinium-3,5-dicarboxyl-ate anion bridges two Cu atoms, forming a two-dimensional coordination polymer. A three-dimensional supra-molecular network is built from N-H⋯O hydrogen bonds involving the pyridinium NH and the carboxyl COO groups.

The IBr(2) (-) anion is almost linear, with a Br-I-Br angle of 178.25 (3)°. The cation is essentially planar (r.m.s. deviation = 0.0067 Å). In the crystal, each Br(-) anion links two cations via N-H⋯Br⋯H-N hydrogen-bonding inter-actions.

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.
