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

ABSTRACT: 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. The geometry around the Cu(II) ion is highly distorted with the range of Cl-Cu-Cl angles being 94.94?(1)-141.03?(1)°. The crystal structure is stabilized by N-H?Cl and C-H?Cl hydrogen bonds. In the three-dimensional network, cations and anions pack in the lattice so as to generate chains of [CuCl4](2-) anions separated by two orientations of cation layers, which are inter-locked through ?-? stacking contacts between pairs of pyridine rings, with centroid-centroid distances of 3.7874?(7)?Å.

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 ?-? 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(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.

Project description:In the title compound, (C(5)H(7)N(2))(2)[CoCl(4)], the cobalt(II) ion is coordinated by four chloride ions in a slightly distorted tetra-hedral geometry. The crystal packing is stabilized by inter-molecular N-H?Cl hydrogen bonding, forming a three-dimensional network. The crystal was a non-merohedral twin emulating tetra-gonal symmetry, but being in fact ortho-rhom-bic.

Hybrid organic-inorganic crystal structure of 4-(di-methyl-amino)-pyridinium di-methyl-ammonium tetra-chlorido-lead(II).

Project description:The title compound, (C2H8N)(C7H11N2)[PbCl4], is a hybrid organic-inorganic material. It crystallizes in the space group C2/c and contains one half of a mol-ecule of lead chloride, 4-(di-methyl-amino)-pyridinium, and di-methyl-ammonium in the asymmetric unit. The crystal structure exhibits chains of lead chloride capped by 4-(di-methyl-amino)-pyridinium and di-methyl-ammoium by hydrogen bonding. This creates a one-dimensional zipper-like structure down the a axis. The crystal structure is examined and compared to a similar structure containing lead chloride and di-methyl-benzene-1,4-diaminium.

Crystal structure, Hirshfeld surface analysis and physicochemical characterization of bis-[4-(di-methyl-amino)-pyridinium] di-μ-chlorido-bis[di-chlorido-mercurate(II)].

Project description:The title mol-ecular salt, (C7H11N2)2[Hg2Cl6], crystallizes with two 4-(di-methyl-amino)-pyridinium cations (A and B) and two half hexa-chlorido-dimercurate(II) anions in the asymmetric unit. The organic cations exhibit essentially the same features with an almost planar pyridyl ring (r.m.s. deviations of 0.0028 and 0.0109 Å), which forms an inclined dihedral angle with the dimethyamino group [3.06 (1) and 1.61 (1)°, respectively]. The di-methyl-amino groups in the two cations are planar, and the C-N bond lengths are shorter than that in 4-(di-methyl-amino)-pyridine. In the crystal, mixed cation-anion layers lying parallel to the (010) plane are formed through N-H⋯Cl hydrogen bonds and adjacent layers are linked by C-H⋯Cl hydrogen bonds, forming a three-dimensional network. The analyses of the calculated Hirshfeld surfaces confirm the relevance of the above inter-molecular inter-actions, but also serve to further differentiate the weaker inter-molecular inter-actions formed by the organic cations and inorganic anions, such as π-π and Cl⋯Cl inter-actions. The powder XRD data confirms the phase purity of the crystalline sample. Furthermore, the vibrational absorption bands were identified by IR spectroscopy and the optical properties were studied by using optical UV-visible absorption spectroscopy.

In the cation, the dihedral angles between the phenyl rings and the plane defined by the central guanidinium fragment are in the range 51.9 (4)-64.4 (3)°. N-H⋯Cl hydrogen bonds assemble the ions into infinite chains running along the b axis.

Crystal structure and Hirshfeld surface analysis of bis-(2,6-di-amino-pyridinium) tetra-chlorido-cobaltate(II).

Project description:In the title mol-ecular salt, (C5H8N3)2[CoCl4], the cations are protonated at their pyridine N atoms and the anion is an almost regular tetra-hedron. The crystal structure consists of alternating inorganic layers, built from tetra-chlorido-cobaltate anions, and organic layers formed by protonated cations of 2,6-di-amino-pyridinium. The crystal packing is governed by C/N-H⋯Cl hydrogen-bonding inter-actions between the organic and the inorganic ions and Cl⋯Cl inter-actions. Moreover, the cations show a π-π stacking inter-action [inter-centroid distance = 3.763 (2) Å]. The prevalence of these inter-actions is illustrated by an analysis of the three-dimensional Hirshfeld surface and by two-dimensional fingerprint plots.

Bis(2-amino-4-methyl-pyridinium) bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II).

Project description:The asymmetric unit of the title compound, (C(6)H(9)N(2))(2)[Cu(C(7)H(3)NO(4))(2)], contains half of a [Cu(pydc)(2)](2-) (pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid) anion and one protonated 2-amino-4-methyl-pyridine (2a4mpH)(+) counter-ion. The anion is a six-coordinated complex with a distorted CuN(2)O(4) octa-hedral geometry around the Cu(II) ion. N-H⋯O and C-H⋯O hydrogen bonds along with π-π contacts between the pyridine rings of the (2a4mpH)(+) cations [centroid-centroid distance = 3.573 (2) Å] stabilize the crystal structure.
