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

ABSTRACT: 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).

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.

1-Phenyl-piperazine-1,4-diium bis-(hydrogen sulfate).

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. In the crystal, the 1-phenyl-piperazine-1,4-diium cations are anchored between chains formed by the sulfate entities via inter-molecular bifurcated N-H?(O,O) and weak C-H?O hydrogen bonds. These hydrogen bonds contribute to the cohesion and stability of the network of the crystal structure.

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

Project description: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 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:In the title compound, [Fe(2)(C(5)H(5))(2)(C(17)H(24)N(2))](CF(3)COO)(2), the cation possesses a crystallographically imposed inversion centre. The methyl group is disordered over two positions of equal occupancy. The Fe-C bond lengths to the two cyclo-penta-diene rings vary from 2.025?(6) to 2.044?(6)?Å. Inter-molecular N-H?O and C-H?O hydrogen bonds link the cations and anions into a three-dimensional network.

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.

Bis(1-methyl-piperazine-1,4-diium) tetra-chloridocuprate(II).

Project description:The title compound, (C(5)H(14)N(2))[CuCl(4)], was synthesized by hydro-thermal reaction of CuCl(2) with 1-methyl-piperazine in an HCl/water solution. Both amine N atoms are protonated. The piperazine ring adopts a chair conformation. The Cu-Cl distances in the tetrahedral anion are in the range 2.2360?(7)-2.2732?(7)?Å. In the crystal, moderately strong and weak inter-molecular N-H?Cl hydrogen bonds link the anion and cation units into an infinite two-dimensional network parallel to the ab plane.

1-Methyl-piperazine-1,4-diium dipicrate.

Project description:IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 1-methyl-piperazine-1,4-diium bis-(2,4,6-trinitro-phen-ol-ate)], C(5)H(14)N(2) (2+)·2C(6)H(2)N(3)O(7) (-), the ionic components are connected by relatively strong N-H⋯O hydrogen bonds into centrosymmetric six-membered conglomerates, which comprise two dications and four anions. Besides Coulombic inter-actions, only weak C-H⋯O inter-actions and some stacking between picrates (separation between the planes of ca. 3.4 Å but only a small overlapping) can be identified between these 'building blocks' of the crystal structure. The piperazine ring adopts a chair conformation with the methyl substituent in the equatorial position. In the picrate anions, the twist angles of the nitro groups depend on their positions relative to the phenolate O atom: it is much smaller for the NO(2) groups para to the C-O(-) group [15.23 (9)and 3.92 (14)°] than for the groups in the ortho positions [28.76 (13)-39.84 (11)°].
