Bis(2-amino-3-nitro-pyridinium) dichromate(VI).

ABSTRACT: The title compound, (C(5)H(6)N(3)O(2))(2)[Cr(2)O(7)], consists of 2-amino-3-nitro-pyridinium cations and discrete dichromate anions linked together by N-H?O and C-H?O hydrogen bonds, forming thick layers parallel to (101). Layer cohesion is ensured by N-H?O hydrogen bonding in addition to electrostatic and van der Waals inter-actions, forming a three-dimensional framework. The dichromate anion is located on a twofold axis that passes through its bridging O atom.

Bis(4-amino-pyridinium) dichromate(VI).

Project description:The asymmetric unit of the title salt, (C5H7N2)2[Cr2O7], contains four independent cations and two independent dichromate anions. The crystal structure consists of discrete dichromate anions with an eclipsed conformation stacked in layers parallel to (010) at y = 1/4 and y = 3/4. These layers are linked via 4-amino-pyridinium cations by N-H?O and weak C-H?O hydrogen bonds, forming a three-dimensional supra-molecular network. In addition, ?-? inter-actions are present in this structure; the shortest distance separating mean planes through 4-amino-pyridinium cations is 3.679?(6)?Å.

Crystal structure of bis[4-(di-methyl-amino)-pyridinium] bis(2-nitro-benzoate) trihydrate.

Project description:The title salt, 2C7H11N2 (+)·2C7H4NO4 (-)·3H2O, crystallized with two anions and two cations in the asymmetric unit, together with three water mol-ecules. Both 4-di-methyl-amino-pyridinium cations are protonated at their pyridine N atoms with the plane of the N(CH3)2 hetero atoms inclined to the pyridine ring by 4.5 (2) and 1.4 (2)°. In the 2-nitro-benzoate anions, the carboxyl and nitro groups are inclined to their respective benzene rings by 77.1 (3) and 20.0 (3)°, and 75.8 (2) and 20.9 (3)°. In the crystal, the anions are linked via O-H⋯O hydrogen bonds involving the water mol-ecules, forming chains along [100]. The cations are linked to these chains by N-H⋯O hydrogen bonds. The chains are linked via C-H⋯O hydrogen bonds and C-H⋯π and π-π inter-actions [inter-centroid distances range from 3.617 (1) to 3.851 (1) Å], forming a three-dimensional structure.

2-Amino-3-nitro-pyridinium perrhenate.

Project description:In the title mol-ecular salt, (C(5)H(6)N(3)O(2))[ReO(4)], the cations and tetrahedral anions are linked by trifurcated N-H?(O,O,O) and bifurcated N-H?(O,O) hydrogen bonds, as well as weak C-H?O inter-actions. This results in alternating corrugated inorganic and organic layers in the crystal.

Crystal structure of 1,4-bis-(3-ammonio-prop-yl)piperazine-1,4-diium bis-[dichromate(VI)].

Project description:The asymmetric unit of the organic-inorganic title salt, (C10H28N4)[Cr2O7]2, comprises one half of an 1,4-bis-(3-ammonio-prop-yl)piperazinediium cation (the other half being generated by the application of inversion symmetry) and a dichromate anion. The piperazine ring of the cation adopts a chair conformation, and the two CrO4 tetra-hedra of the anion are in an almost eclipsed conformation. In the crystal, the cations and anions form a layered arrangement parallel to (001). N-H⋯O hydrogen bonds between the cations and anions and additional C-H⋯O inter-actions lead to the formation of a three-dimensional network structure.
