2-Amino-6-methyl-pyridinium trans-di-aqua-dioxalatochromate(III) monohydrate.

ABSTRACT: In the title compound, (C6H9N2)[Cr(C2O4)2(H2O)2]·H2O, the Cr(III) atom adopts a slightly distorted octa-hedral coordination environment defined by two chelating oxalate ligands in the equatorial plane and two water mol-ecules in axial positions. A three-dimensional network is generated by inter-molecular N-H?O and O-H?O hydrogen-bonding interactions involving the cation, the complex anion and the lattice water molecule.

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.

Project description:In the title compound, (C(7)H(11)N(2))[Er(H(2)O)(8)]Cl(4)·H(2)O, the asymmetric unit consists of one 4-(dimethyl-amino)-pyridinium and one octa-aqua-erbium cation balanced by four Cl(-) anions, and one water mol-ecule. The 4-(dimethyl-amino)-pyridinium cation is protonated at the pyridine N atom. The dimethyl-amino group (C/N/C) lies close to the plane of the pyridinium ring, making a dihedral angle of 4.5?(3)°. In the crystal, the [Er(H(2)O)(8)](3+) cations are linked via O-H?O and O-H?Cl hydrogen bonds, forming two-dimensional networks propagating in the ab plane. These networks are linked via O-H?O and O-H?Cl hydrogen bonds, forming a three-dimensional network. The 4-(dimethyl-amino)-pyridinium cations are located in the cavities and are linked to the framework via N-H?Cl, C-H?O and C-H?Cl hydrogen bonds.

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.

Crystal structure of bis-[4-(di-methyl-amino)-pyridinium] aqua-bis-(oxalato)oxidovanadate(IV) dihydrate.

Project description:The title organic-inorganic hybrid salt, (C7H11N2)2[V(C2O4)2O(H2O)]·2H2O, shows a distorted octa-hedral coordination environment for the vanadium(IV) atom in the anion (point group symmetry 2), with four O atoms from two symmetry-related chelating oxalate dianions and two O atoms in trans configuration from a coordinating water mol-ecule and a terminal vanadyl O atom. In the crystal, (001) layers of cations and anions alternate along [001]. The anionic layers are built up by inter-molecular O-H⋯O hydrogen bonds involving the coordinating and solvent water mol-ecules. The cationic layers are linked to the anionic layers via N-H⋯O hydrogen bonds between the pyridinium group and the non-coordinating O atoms of the oxalate group. The 4-(di-methyl-amino)-pyridinium cations are also engaged in π-π stacking with their anti-parallel neighbours [centroid-to-centroid distance = 3.686 (2) Å]. Considering all supra-molecular features, a three-dimensional network structure is accomplished.

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.
