2-Amino-pyridinium trans-diaqua-bis-(oxalato-κ(2)O,O)chromate(III).

ABSTRACT: In the title hybrid salt, (C(5)H(7)N(2))[Cr(H(2)O)(2)(C(2)O(4))(2)], the Cr(III) ion is coordinated in a slightly distorted octa-hedral environment by four O atoms from two oxalate ligands in the equatorial plane and by two water O atoms in the axial sites. The 2-amino-pyridinium cation is disordered over two sets of sites in a 0.800 (7):0.200 (7) ratio. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect the components into a three-dimensional network. The crystal studied was an inversion twin with components in a ratio 0.75 (2):0.25 (2).

4-(Dimethyl-amino)-pyridinium trans-diaqua-bis-[oxalato(2-)-κO,O]chromate(III).

Project description:In the title salt, (C(7)H(11)N(2))[Cr(C(2)O(4))(2)(H(2)O)(2)], the asymmetric unit contains one half-cation and one half-anion. The Cr atom, the C and N atoms involved in C- N(exocyclic) bonding and the N and H atoms of N-H groups lie on twofold rotation axis. The Cr(III) atom of the complex anion is six-coordinated in a distorted (4 + 2) octa-hedral geometry with four equatorial O atoms of two nearly coplanar oxalate and two quasi-axial aqua O atoms. In the crystal, the protonated N atoms of the pyridine rings are hydrogen bonded to the carbonyl O atoms of the anions, forming chains along [010]. These chains are connected by lateral O-H⋯O hydrogen bonds, stabilizing the structure.

Pyridinium cis-diaqua-bis-(oxalato-κ(2)O,O')chromate(III).

Project description:The title compound, (C(5)H(6)N)[Cr(C(2)O(4))(2)(H(2)O)(2)], contains one protonated pyridine mol-ecule and one [Cr(C(2)O(4))(2)(H(2)O)(2)](-) complex anion in the asymmetric unit. The Cr(III) in the complex anion is coordinated in a distorted octa-hedral environment by two O atoms from two cis water mol-ecules and four O atoms from two chelating oxalate dianions. The crystal packing is stabilized by inter-molecular N-H⋯O(oxalate) and O-H⋯O(oxalate) hydrogen bonds and by π-π stacking inter-actions (centroid-centroid distance = 3.602 Å) between pyridine rings, thereby building up a three-dimensional network.

3-Amino-pyridinium trans-diaqua-dioxalato-chromate(III).

Project description:In the structure of the title compound, (C?H?N?)[Cr(C?O?)?(H?O)?], two crystallographically independent formula units are present. Both chromium atoms are six-coordinated in a distorted octa-hedral geometry by two chelating equatorial oxalato ligands and two axial water mol-ecules. The [Cr(C?O?)?(H?O)?]? anions and C?H?N? ? cations are linked through a complex three-dimensional hydrogen-bonding network consisting of N-H?O and O-H?O inter-actions.

Pyridinium trans-di-aqua-bis-[oxalato(2-)-κ(2) O (1),O (2)]chromate(III) urea monosolvate.

Project description:The asymmetric unit of the title solvated mol-ecular salt, (C5H6N)[Cr(C2O4)2(H2O)2]·CO(NH2)2, contains half a formula unit. Each component is completed by crystallographic twofold symmetry: in the cation, one C and the N atom lie on the rotation axis; in the anion, the Cr(III) ion lies on the axis; in the solvent mol-ecule, the C and the O atom lie on the axis. The aqua ligands are in a trans disposition in the resulting CrO6 octa-hedron. In the crystal, the components are linked by O-H⋯O, N-H⋯O and N-H⋯(O,O) hydrogen bonds, generating a three-dimensional network.

4-Amino-pyridinium trans-diaqua-dioxalatochromate(III) monohydrate.

Project description:In the non-centrosymmetric structure of the title compound, (C(5)H(7)N(2))[Cr(C(2)O(4))(2)(H(2)O)(2)]·H(2)O, the Cr(III) ion has a slightly distorted octa-hedral coordination environment defined by two chelating oxalato ligands in equatorial positions and two water mol-ecules in axial positions. An extensive three-dimensional network of hydrogen bonds involving all the water mol-ecules, the 4-amino-pyridinium cation and some of the oxalate O atoms contributes to the stabilization of the structure. π-π inter-actions between adjacent pyridine rings provide additional stability of the crystal packing, with a closest distance between pyridine mean planes of 3.613 (1) Å.

Crystal structure of tris-[4-(di-methyl-amino)-pyridinium] tris-(oxalato-κ(2) O,O')chromate(III) tetra-hydrate.

Project description:In the title hybrid salt, (C7H11N2)3[Cr(C2O4)3]·4H2O, the central Cr(III) ion of the complex anion (point group symmetry 2) is coordinated by six O atoms from three chelating oxalate(2-) ligands in a slightly distorted octa-hedral coordination sphere. The Cr-O bond lengths vary from 1.9577 (11) to 1.9804 (11) Å, while the chelate O-Cr-O angles range from 82.11 (6) to 93.41 (5)°. The 4-(di-methyl-amino)-pyridinium cations (one situated in a general position and one on a twofold rotation axis) are protonated at the pyridine N atoms. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the cations and anions into a three-dimensional network. π-π inter-actions between the pyridine rings of adjacent cations provide additional stabilization of the crystal packing, with the closest centroid-to-centroid distances being 3.541 (1) and 3.575 (1) Å.

Pyridinium diaqua-bis-(methyl-enediphospho-nato-κO,O')chromate(III) tetra-hydrate.

Project description:In the title complex, (C(5)H(6)N)[Cr(CH(4)O(6)P(2))(2)(H(2)O)(2)]·4H(2)O, the Cr(III) atom, lying on an inversion centre, is coordinated by two bidentate methyl-ene diphospho-nate ligands and two water molecules in a distorted octa-hedral coordination geometry. The pyridinium cation is located on an inversion centre, with an N atom and a C atom sharing a position each at a half occupancy. A three-dimensional network is constructed by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds between the pyridin-ium cation, complex anion and uncoordinated water mol-ecules.

The ionic components are connected via inter-molecular N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.

Project description:The asymmetric unit of the ionic title compound, (C(6)H(7)N(2)O)[Bi(C(7)H(3)NO(4))(2)(H(2)O)(2)]·H(2)O or (acpyH)[Bi(pydc)(2)(H(2)O)(2)]·H(2)O, contains an [Bi(pydc)(2)(H(2)O)(2)](-) anion (where pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid), a protonated 3-(amino-carbon-yl)pyridine as counter-ion, (acpyH)(+), and one uncoordinated water mol-ecule. The anion is an eight-coordinate complex with a square-anti-prismatic geometry around the Bi(III) atom. In the crystal, extensive O-H⋯O and N-H⋯O hydrogen bonds, as well as ion pairing, C=O⋯π inter-actions [O⋯centroid distance = 3.583 (5) Å], π-π stacking [centroid-centroid distance = 3.864 (3) Å], and C-H⋯π and C-H⋯O inter-actions, play an important role in the formation and stabilization of the three-dimensional supra-molecular structure.
