Crystal structure of piperazine-1,4-diium bis-(4-amino-benzene-sulfonate).

ABSTRACT: The asymmetric unit of the title salt, C4H12N2 (2+)·2C6H6NO3S(-), consists of half a piperazindiium dication, located about an inversion centre, and a 4-amino-benzene-sulfonate anion. The piperazine ring adopts a chair conformation. In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional framework. Within the framework there are C-H⋯π inter-actions and the N-H⋯O hydrogen bonds result in the formation of R 4 (4)(22) and R 3 (4)(13) ring motifs.

Crystal structure of 2-methyl-piperazine-1,4-diium bis-(hydrogen maleate).

Project description:In the title salt, C5H14N2 (2+)·2C4H3O4 (-), the asymmetric unit contains two independent 2-methyl-piperazinium dications, which comprise a racemic pair, and four hydrogen maleate monoanions. In the roughly planar hydrogen maleate anions, intra-molecular O-H⋯O hydrogen bonds generate S(7) rings. In the crystal, the four independent anions are linked to the 2-methyl-piperazinium cations through N-H⋯O hydrogen bonds, forming two-dimensional layered structures lying parallel to (001).

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.

Project description:The asymmetric unit of the title salt, C(4)H(12)N(2) (2+)·2C(9)H(5)O(6) (-), comprises one half of the piperazine-1,4-diium dication lying on an inversion centre and one 3,5-dicarboxy-benzoate anion.

trans-2,5-Di-methyl-piperazine-1,4-diium bis(perchlorate) dihydrate: crystal structure and Hirshfeld surface analysis.

Project description:The asymmetric unit of the title hydrated mol-ecular salt, C6H16N2 (2+)·2ClO4 (-)·2H2O, contains a half dication (completed by inversion symmetry), a perchlorate anion and a water mol-ecule. The extended structure consists of infinite chains of formula [(ClO4)H2O] n (n) (-) ions extending along the b axis linked by Ow-H⋯O (w = water) hydrogen bonds. These chains are cross-linked by the dications via N-H⋯Ow and weak C-H⋯O hydrogen bonds, thus forming a three-dimensional supra-molecular network. Three-dimensional Hirshfeld surface analysis and two-dimensional fingerprint maps reveal that the structure is dominated by H⋯O/O⋯H and H⋯H contacts.

The solvent water mol-ecule links cations and anions through O-H⋯O and N-H⋯O hydrogen bonds, generating a two-dimensional layer parallel to (10).

Project description:In the title compound, C(10)H(16)N(2) (2+)·2HSO(4) (-), the S atoms adopt slightly distorted tetra-hedral geometry and the diprotonated piperazine ring adopts a chair conformation.
