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

ABSTRACT: 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.

In the structure of the title compound, (C₅H₇N₂)[Cr(C₂O₄)₂(H₂O)₂], 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(C₂O₄)₂(H₂O)₂]⁻ anions and C₅H₇N₂ ⁺ cations are linked through a complex three-dimensional hydrogen-bonding network consisting of N-H⋯O and O-H⋯O inter-actions. ...[more]

4-(Dimethyl-amino)-pyridinium trans-diaqua-bis-[oxalato(2-)-?O,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.

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

Project description: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-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. ?-? 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.

Pyridinium cis-diaqua-bis-(oxalato-?(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 ?-? stacking inter-actions (centroid-centroid distance = 3.602?Å) between pyridine rings, thereby building up a three-dimensional network.

Pyridinium diaqua-bis-(methyl-enediphospho-nato-?O,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.

Project description:In the crystal structure of the title compound, (C(5)H(6)ClN(2))[Cr(C(2)O(4))(2)(H(2)O)(2)]·1.5H(2)O, the Cr(III) atom adopts a distorted octa-hedral geometry being coordinated by two O atoms of two cis water mol-ecules and four O atoms from two chelating oxalate dianions. The cis-diaqua-dioxalatochromate(III) anions, 2-amino-5-chloro-pyridinium cations and uncoordinated water mol-ecules are linked into a three-dimensional supra-molecular array by O-H?O and N-H?O hydrogen-bonding inter-actions. One of the two independent lattice water molecules is situated on a twofold rotation axis.

Pyridinium trans-di-aqua-bis-[oxalato(2-)-?(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.

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?? inter-actions [O?centroid distance = 3.583?(5)?Å], ?-? stacking [centroid-centroid distance = 3.864?(3)?Å], and C-H?? and C-H?O inter-actions, play an important role in the formation and stabilization of the three-dimensional supra-molecular structure.

Imidazolium trans-di-aqua-dioxalato-chromate(III) dihydrate.

Project description:In the title hydrated mol-ecular salt, (C3H5N2)[Cr(C2O4)2(H2O)2]·2H2O, the complete cation is generated by a crystallographic twofold rotation axis, with one C atom lying on the rotation axis. The complete anion is generated by crystallographic inversion symmetry (Cr(III) site symmetry -1), to generate a slightly distorted CrO6 octa-hedron with trans water mol-ecules and chelating oxalate dianions. The oxalate ion is almost planar (r.m.s. deviation = 0.017?Å) and the five-membered chelate ring is a shallow envelope with the metal ion displaced by 0.126?(1)?Å from the ligand atoms. The crystal structure features O-H?O, N-H?O and C-H?O hydrogen bonds, which link the components into a three-dimensional network.
