Crystal structure of bis-(acetonyltri-phenyl-phospho-nium) tetra-chlorido-cobaltate(II).

ABSTRACT: The complex title salt, (C21H20OP)2[CoCl4], is the reaction product of CoCl2 with acetonyltri-phenyl-phospho-nium chloride in aceto-nitrile. In the anion, the Co(II) atom exhibits a typical tetra-hedral environment, with Co-Cl distances ranging from 2.2721?(6) to 2.2901?(6)?Å, and with Cl-Co-Cl angles ranging from 106.12?(2) to 112.24?(2)°. The two phospho-nium cations likewise show the expected tetra-hedral configuration, with P-C distances ranging from 1.785?(2) to 1.8059?(18)?Å and C-P-C angles ranging from 106.98?(8) to 112.85?(15)°. The mol-ecules inter-act in the lattice mainly through Coulombic and van der Waals forces because there is no particular polarity to the charges carried by the cations or anion. In the crystal, the cations and anions are arranged in sheets parallel to (001).

Acetonyltri-phenyl-phospho-nium 2,3,5-tri-phenyl-tetra-zolium tetra-chlorido-cuprate(II).

Project description:The title compound, (C21H20OP)(C19H15N4)[CuCl4], was obtained by reacting CuCl2·2H2O with a mixture of one equivalent of acetonyltri-phenyl-phospho-nium chloride and one equivalent of 2,3,5-tri-phenyl-tetra-zolium chloride in aceto-nitrile. In the structure, the Cu centre in the dianion is bonded to four chloride ligands and adopts a distorted tetra-hedral geometry. The phospho-nium cation likewise adopts the expected tetra-hedral geometry. The tetra-zolium ring forms dihedral angles of 77.68 (10), 26.85 (11) and 66.48 (10)° with the planes of the benzene rings of the substituent groups. In the crystal, weak C-H⋯Cl hydrogen-bonding inter-actions involving both cations and the anion give rise to a three-dimensional supra-molecular structure.

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.].

Crystal structure of bis-(2-methyl-1H-imidazol-3-ium) tetra-chlorido-cobaltate(II).

Project description:The asymmetric unit of the title compound, (C4H7N2)2[CoCl4], consists of two 2-methyl-imidazolium cations and one tetra-hedral [CoCl4](2-) anion. The anions and cations inter-act through N-H⋯Cl hydrogen bonds to define layers with a stacking direction along [100]. Besides van der Waals forces, weak C-H⋯Cl inter-actions between these layers stabilize the crystal packing.

Bis(triethyl-ammonium) tetra-chlorido-cobaltate(II).

Project description:The crystal structure of the title compound, (C(6)H(16)N)(2)[CoCl(4)], is comprised of a tetrahedral [CoCl(4)](2-) anion and two independent triethyl-ammonium cations. The latter are featureless while the [CoCl(4)](2-) anion exhibits typical Co-Cl bond lengths [2.2428?(15)-2.2847?(16)?Å] and a Cl-Co-Cl angular range of 107.58?(6)-112.73?(7)°. In the crystal, N-H?Cl hydrogen bonds between the two crystallographically independent cations and the [CoCl(4)](2-) anion generate discrete ion triplets. The two Co-Cl bonds involved in these inter-actions are slightly longer than the remaining two.

Crystal structure of bis-(4-acetyl-anilinium) tetra-chlorido-cobaltate(II).

Project description:The structure of the title salt, (C8H10NO)2[CoCl4], is isotypic with the analogous cuprate(II) structure. The asymmetric unit contains one 4-acetyl-anilinium cation and one half of a tetra-chlorido-cobaltate(II) anion for which the Co(II) atom and two Cl(-) ligands lie on a mirror plane. The Co-Cl distances in the distorted tetra-hedral anion range from 2.2519?(6) to 2.2954?(9)?Å and the Cl-Co-Cl angles range from 106.53?(2) to 110.81?(4)°. In the crystal, cations are self-assembled by inter-molecular N-H?O hydrogen-bonding inter-actions, leading to a C(8) chain motif with the chains running parallel to the b axis. ?-? stacking inter-actions between benzene rings, with a centroid-to-centroid distance of 3.709?Å, are also observed along this direction. The CoCl4 (2-) anions are sandwiched between the cationic chains and inter-act with each other through inter-molecular N-H?Cl hydrogen-bonding inter-actions, forming a three-dimensional network structure.

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.
