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

ABSTRACT: 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/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[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. 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(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.

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.

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.

Bis(2-amino-4-methyl-pyridinium) tetra-chloridocuprate(II).

Project description:The asymmetric unit of the title compound, (C(6)H(9)N(2))(2)[CuCl(4)], consists of one cation and one half-anion, bis-ected by a twofold rotation axis through the metal center. The anion exhibits a geometry that is inter-mediate between a T(d) and D(4h) arrangement about the Cu atom. The crystal structure contains chains of cations alternating with stacks of anions. The cationic groups inter-act via offset face-to-face π-π stacking, forming chains running along the c axis. The anion stacks are parallel to the cation chains, with no significant inter- nor intra-stack Cl⋯Cl inter-actions. There are several anion-cation hydrogen-bonding inter-actions of the (N-H)(pyridine)⋯Cl and (N-H)(amino)⋯Cl types, connecting the chains of cations to the stacks of anions. Both the N-H⋯Cl and π-π stacking inter-actions [centroid-centroid distances 3.61 (8) and 3.92 (2) Å] contribute to the formation of a three-dimensional supra-molecular architecture.
