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

ABSTRACT: 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.

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.

Bis(2,4-dimethyl-pyridinium) tetra-bromido-mercurate(II).

Project description:The asymmetric unit of the title compound, (C7H10N)2[HgBr4], consists of one cation and one half-anion, bis-ected by a twofold rotation axis passing through the metal atom. The anion exhibits a distorted tetra-hedral arrangement about the Hg(II) atom. In the crystal, the cations and anions are linked by N-H?Br hydrogen-bonding inter-actions along [010]. Cation-cation ?-? stacking and Br?Br inter-molecular inter-actions are absent.

Bis(2,6-diamino-pyridinium) bis-(pyridine-2,6-dicarboxyl-ato)zincate(II) monohydrate.

Project description:In the title hydrated mol-ecular salt, (C(5)H(8)N(3))(2)[Zn(C(7)H(3)NO(4))(2)]·H(2)O, the Zn(II) atom is coordinated by two O,N,O'-tridentate pyridine-2,6-dicarboxyl-ate dianions, generating a slightly distorted trans-ZnN(2)O(4) octa-hedral coordination geometry for the metal ion. In the crystal, a network of O-H?O, N-H?O and C-H?O hydrogen bonds involving the cations, anions and water mol-ecules results in a three-dimensional network.

Bis(3-methyl-pyridinium) tetra-(chlorido/bromido)cuprate(II).

Project description:The structure of the title salt, (C(6)H(8)N)(2)[CuCl(3.4)Br(0.6)], consists of two 3-methyl-pyridinium cations and a distorted tetra-hedral [CuCl(3.4)Br(0.6)](2-) dianion. Substitutional disorder with Br is exhibited for three of the Cl atoms of the anion, giving a mixed chloride/bromide cuprate(II) anion. In the crystal, inter-molecular N-H?Cl hydrogen bonds link two cations to one anion, forming a three-ion aggregate. These are connected into a supra-molecular chain along the b axis via ?-? inter-actions between the pyridinium rings [centroid-centroid distance = 3.743?(3)?Å].

Bis-(2-amino-6-methyl-pyridinium) tetra-bromido-cuprate(II).

Project description:In the crystal structure of the title compound, (C(6)H(9)N(2))(2)[CuBr(4)], the geometry around the Cu atom is inter-mediate between tetra-hedral (T(d)) and square planar (D(4h)). Each [CuBr(4)](2-) anion is connected non-symmetrically to four surrounding cations through N-H⋯X (pyridine and amine proton) hydrogen bonds, forming chains of the ladder-type running parallel to the crystallographic b axis. These layers are further connected by means of offset face-to-face inter-actions (parallel to the a axis), giving a three-dimensional network. Cation π-π stacking [centroid separations of 3.69 (9) and 3.71 (1) Å] and Br⋯aryl inter-actions [3.72 (2) and 4.04 (6) Å] are present in the crystal structure. There are no inter-molecular Br⋯Br inter-actions.

Bis[2,6-bis-(2-meth-oxy-phen-yl)pyridinium] di-μ-bromido-bis-[dibromidocuprate(II)].

Project description:The title salt, (C(19)H(18)NO(2))(2)[Cu(2)Br(6)], was obtained from an attempt to synthesize the copper(II) complex of 2,6-bis-(2-meth-oxy-phen-yl)pyridine (L) from a reaction between CuBr(2) and one equivalent of L in CH(2)Cl(2) at room temperature. The resulting compound is the salt of the 2,6-bis-(2-meth-oxy-phen-yl)pyridinium cation and 0.5 equivalents of a hexa-bromido-dicuprate(II) dianion. Both meth-oxy groups of the cationic pyridinium moiety are directed towards the N atom of the pyridine ring as a result of intra-molecular N-H⋯O hydrogen bonds. The centrosymmetric hexabromidodicuprate dianion possesses a distorted tetra-hedral geometry at the copper ion. The Cu-Br bond lengths are 2.3385 (7) and 2.3304 (7) Å for the terminal bromides, whereas the bond length between the Cu atom and two bridging bromides is slightly longer [2.4451 (6) Å].
