Bis(2-amino-5-chloro-pyridinium) tetra-chloridozincate.

ABSTRACT: The asymmetric unit of the title compound, (C(5)H(6)ClN(2))(2)[ZnCl(4)], contains two 2-amino-5-chloro-pyridinium cations and one [ZnCl(4)](2-) dianion which are held together by N-H?Cl and C-H?Cl hydrogen bonds. The [ZnCl(4)](2-) anions have a distorted tetra-hedral geometry. Weak inter-molecular ?-? stacking inter-actions exist between neighbouring aromatic rings of the cations with a centroid-centroid distance of 3.712?(7)?Å.

The asymmetric unit of the title compound, (C(5)H(6)ClN(2))(2)[ZnCl(4)], contains two 2-amino-5-chloro-pyridinium cations and one [ZnCl(4)](2-) dianion which are held together by N-H⋯Cl and C-H⋯Cl hydrogen bonds. The [ZnCl(4)](2-) anions have a distorted tetra-hedral geometry. Weak inter-molecular π-π stacking inter-actions exist between neighbouring aromatic rings of the cations with a centroid-centroid distance of 3.712 (7) Å. ...[more]

Bis[4-(dimethyl-amino)-pyridinium] tetra-chloridozincate.

Project description:In the title compound, (C(7)H(11)N(2))(2)[ZnCl(4)], [ZnCl(4)](2-) anions and 4-(dimethyl-amino)-pyridinium cations are held together by various inter-molecular inter-actions including Coulombic attraction, hydrogen bonding and π-π stacking inter-actions. Three Cl atoms of the [ZnCl(4)](2-) tetra-hedron act as acceptors in N-H⋯Cl hydrogen bonds. The hydrogen bonds, both of which are bifurcated, lead to the formation of a three-dimensional network. Within the network, inter-molecular π-π stacking inter-actions with a centroid-centroid distance of 3.5911 (7) Å arrange the 4-(dimethyl-amino)-pyridinium cations into anti-parallel dimers.

Crystal structure of bis-(2-amino-5-chloro-pyridinium) tetra-chlorido-cobaltate(II).

Project description:The title salt, (C5H6ClN2)2[CoCl4], was synthesized by slow evaporation of an aqueous solution at room temperature. The asymmetric unit consists of two essentially planar (C5H6ClN2)(+) cations [maximum deviations = 0.010?(3) and 0.014?(3)?Å] that are nearly perpendicular to each other [dihedral angle = 84.12?(7)°]. They are bonded through N-H?Cl hydrogen bonds to distorted [CoCl4](2-) tetra-hedra, leading to the formation of undulating layers parallel to (100). The structure is isotypic with the Zn analogue [Kefi et. al (2011). Acta Cryst. E67, m355-m356.].

Bis(4-chloro-pyridinium) tetra-chlorido-nickelate(II).

Project description:In the title compound, (C(5)H(5)ClN)(2)[NiCl(4)], the dianion lies on a twofold rotation axis. Two cations are linked to each anion by classical N-H⋯Cl hydrogen bonds, and short Cl⋯Cl contacts and Cl⋯π stacking inter-actions [with distances of 3.376 (2) and 3.684 (2) Å, respectively] extend this pattern into a chain. The [NiCl(4)](2-) anion shows significant deviation from ideal tetra-hedral geometry.

Project description:The crystal structure of the title compound, (C(25)H(21)ClP)(2)[ZnCl(4)]·3H(2)O, consists of tetra-hedral phosphonium cations and tetra-hedral zincate anions; the water mol-ecules form weak hydrogen bonds to the anions. Two of the water mol-ecules are disordered over three sites in a 0.68:0.55:0.77 ratio.

2-Acetyl-pyridinium 3-amino-2-chloro-pyridinium tetra-chloridocobaltate(II).

Project description:In the title complex, (C(5)H(6)ClN(2))(C(7)H(8)NO)[CoCl(4)], the Co(II) ions are tetra-hedrally coordinated. The crystal structure is built from hydrogen-bonded centrosymmetric tetra-mers of tetra-chloridocobaltate(II) dianions and 3-amino-2-chloro-pyridinium cations, additionally strengthened by significant ?-? stacking of pyridinium rings [interplanar distance 3.389?(3)?Å]. The tetra-mers are linked by N-H?Cl hydrogen bonds into chains; the second kind of cations, viz. 2-acetyl-pyridinium, are connected by N-H?Cl hydrogen bonds to both sides of the chain. The Co-Cl bond lengths in the dianion correlate with the number of hydrogen bonds accepted by the Cl atom. An intramolecular C-H?Cl interaction is also present.

Bis(2-amino-1,3-benzothia-zol-3-ium) tetra-chloridozincate(II).

Project description:The asymmetric unit of the title compound, (C(7)H(7)N(2)S)(2)[ZnCl(4)], contains a network of 2-amino-benzothia-zolium cations and tetra-hedral [ZnCl(4)](2-) anions. The crystal packing is influenced by cation-to-anion N-H?Cl and C-H?Cl hydrogen bonds. The [ZnCl(4)](2-) anions have a distorded tetra-hedral geometry. Inter-molecular ?-? stacking inter-actions are present between neighboring benzene rings, thia-zole and benzene rings and neighboring thia-zole rings [centroid-centroid distances = 3.711?(2), 3.554?(1), 3.536?(2) and 3.572?(1)?Å].

Bis[4-(dimethyl-amino)pyridinium] tetra-bromidobis(4-chloro-phen-yl)stannate(IV)-4-bromo-chloro-benzene (1/1).

Project description:In the title compound, (C(7)H(11)N(2))(2)[SnBr(4)(C(6)H(4)Cl)(2)]·C(6)H(4)BrCl, the Sn(IV) atom in the tetra-bromidobis(4-chloro-phen-yl)stannate(IV) anion lies on a centre of inversion. The distances between the 4-(dimethyl-amino)pyridinium N atom and the Br atoms of the anion are 3.450 (2) and 3.452 (2) Å, suggesting weak hydrogen bonding. The 4-bromo-chloro-benzene solvent mol-ecule, which is a bromination by-product from the reaction, is disordered about a twofold rotation axis with approximately equal occupancy.
