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

ABSTRACT: 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 ?-? 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(3-methyl-pyridinium) tetra-chlorido-cuprate(II).

Project description:The title compound, (C(6)H(8)N)(2)[CuCl(4)], is composed of two 3-methyl-pyridinium cation and one tetra-chloridocuprate(II) anion. The geometry around the copper(II) ion is that of a distorted tetra-hedron. In the crystal structure, the anions and cations are linked by three different N-H?Cl hydrogen bonds. In addition, the crystal structure exhibits aromatic ?-? inter-actions between the pyridinium rings of two discrete units [centroid-centroid distance = 3.704?(2)?Å].

Bis(1-methyl-piperidinium) tetra-chlorido-cuprate(II).

Project description:The structure of the title compound, (C(6)H(14)N)(2)[CuCl(4)], consists of two inequivalent 1-methyl-piperidinium cations and a flattened tetra-hedral [CuCl(4)](2-) anion. Each organic cation exhibits a chair conformation with the methyl group in the equatorial position. They are segregated into alternating layers parallel to (100) and stacked along [100]. The first cation is arranged in parallel stacks in a herringbone pattern with rows of [CuCl(4)](2-) anions fitting between the stacks and with a Cl(-) ion directed into the inter-ior of the layer. The second organic cation forms distorted hcp layers that separate the other organic cation/[CuCl(4)](2-) slabs. N-H?Cl hydrogen bonding between the cations and the anions consolidates the crystal packing.

Bis[4-(di-methyl-amino)-pyridinium] tetra-chlorido-cuprate(II).

Project description:The asymmetric unit of the title salt, (C7H11N2)2[CuCl4], comprises half a tetrahedral tetra-chlorido-cuprate anion, being located on a twofold axis, and a protonated 4-(di-methyl-amino)-pyridine cation.
