Bis(1-methyl-piperazine-1,4-diium) di-?-bromido-bis-[tetra-bromido-bismuthate(III)] dihydrate.

ABSTRACT: In the title hydrated salt, (C5H14N2)2[Bi2Br10]·2H2O, the com-plete [Bi2Br10](4-) biocta-hedron is generated by crystallographic inversion symmetry. The diprotonated piperazine ring adopts a chair conformation, with the methyl group occupying an equatorial position. In the crystal, the tetra-anions and water mol-ecules are linked by O-H?Br and O-H?(Br,Br) hydrogen bonds to generate [100] chains. The chains are crosslinked by N-H?Br, N-H?O and C-H?Br hydrogen bonds originating from the piperazinediium dications, thereby forming a three-dimensional network.

In the title hydrated salt, (C5H14N2)2[Bi2Br10]·2H2O, the com-plete [Bi2Br10](4-) biocta-hedron is generated by crystallographic inversion symmetry. The diprotonated piperazine ring adopts a chair conformation, with the methyl group occupying an equatorial position. In the crystal, the tetra-anions and water mol-ecules are linked by O-H⋯Br and O-H⋯(Br,Br) hydrogen bonds to generate [100] chains.

Piperazine-1,4-diium bis-[tetra-chlorido-aurate(III)] dihydrate.

Project description:In the title compound, (C(4)H(12)N(2))[AuCl(4)](2)·2H(2)O, the Au(III) atom has a square-planar geometry. The piperazinium dication lies on an inversion centre and adopts a typical chair conformation. In the crystal, a combination of N-H?O, N-H?Cl and O-H?Cl hydrogen bonds results in the formation of a three-dimensional network.

Piperazine-1,4-diium bis-(perchlorate) dihydrate.

Project description:The asymmetric unit of the title compound, C(4)H(12)N(2) (2+)·2ClO(4) (-)·2H(2)O, contains half of a piperazinediium cation, one perchlorate anion and one water mol-ecule. The diprotonated piperazine ring, which is completed by crystallographic inversion symmetry, adopts a chair conformation. In the crystal structure, the cations and anions are linked by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.

Bis[1-(2,3-di-methyl-phen-yl)piperazine-1,4-diium] bis-(oxonium) cyclo-hexa-phosphate dihydrate.

Project description:In the title compound, 2C12H20N2 (2+)·2H3O(+)·P6O18 (6-)·2H2O, a protonated water mol-ecule bridges the centrosymmetrical anionic P6O18 ring via O-H?O hydrogen bonds. The centrosymmetric hydrogen-bonded rings formed by four oxonium cations and four phosphate anions can be described by an R 4 (8)(36) graph-set motif. The ring motifs are connected by hydrogen bonds into inorganic layers perpendicular to [100]. The 1-(2,3-di-methyl-phen-yl)piperazine-1,4-diium cations are located between the layers, compensating their negative charge and establishing N-H?O hydrogen bonds with the O atoms of the anionic framework.

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.

Tris(piperazine-1,4-diium) bis-[hexa-chloridoindate(III)] tetra-hydrate.

Project description:The asymmetric unit of the title compound, (C(4)H(12)N(2))(3)[InCl(6)](2)·4H(2)O, consists of one and half independent piperazinium cations, an hexa-chloridoindate anion and two mol-ecules of water. The In(III) ion is six-coordinated and forms a quasi-regular octa-hedral arrangement. In the crystal, alternating layers of cations and anions are arranged parallel to (10[Formula: see text]) and are linked with the water mol-ecules via intra- and inter-molecular N-H⋯O, O-H⋯Cl, C-H⋯O and N-H⋯Cl hydrogen bonds, forming a complex three-dimensional network. Additional stabilization within the layers is provided by weak inter-molecular C-H⋯Cl inter-actions.

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.

catena-Poly[[[tetra-aqua-magnesium]-trans-?-[(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nato] hemihydrate].

Project description:The structure of the title polymer, }[Mg(C6H14N2O6P2)(H2O)4]·0.5H2O} n , is based on centrosymmetric MgO6 octahedra, which are linked by [(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nate ligands, forming chains parallel to [1-1-1]. These chains are connected via hydrogen bonds primarily formed between the phospho-nate groups and water mol-ecules. The latter constitute four of the corners of the MgO6 polyhedra and bind to the O atoms of the phospho-nate groups of neighbouring chains. The lattice water molecule is disordered around an inversion centre, exhibiting an occupancy of 0.25.
