4-(4-Carboxy-benz-yl)-1-methyl-piperazin-1-ium picrate.

Project description:The title compound, C(13)H(19)N(2)O(2) (+)·C(6)H(2)N(3)O(7) (-), is a salt obtained by cocrystallization of 4-[(4-methyl-piperazin-1-yl)meth-yl]benzoic acid and picric acid. The cations adopt an 'L-shaped' conformation and are linked into chains along [010] by O-H?N hydrogen bonds. The NH group of each piperazinium ring forms a hydrogen bond to the phenolate O atom of a picrate anion, and the picrate anions form face-to-face contacts with an inter-planar separation of 3.023?(1)?Å.

Project description:The asymmetric unit of the title compound, C(17)H(20)ClN(2) (+)·C(6)H(2)N(3)O(7) (-)·H(2)O, contains a piperazin-1-ium cation, a picrate anion and one solvent water mol-ecule. The piperazene ring is protonated at one N atom and adopts a highly distorted chair conformation with the chloro-pheny(phen-yl)methyl substituent on the second N atom in an equatorial position. The crystal structure is stabilized by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds.

4-(Methyl-sulfon-yl)piperazin-1-ium chloride.

Project description:In the title mol-ecular salt, C(5)H(13)N(2)O(2)S(+)·Cl(-), the complete cation is generated by crystallographic mirror symmetry, with both N atoms, the S atom and one C atom lying on the reflecting plane. The chloride ion also lies on the mirror plane. The piperazinium ring adopts a chair conformation and the N-S bond adopts an equatorial orientation. In the crystal structure, the component ions are linked into a three-dimensional framework by inter-molecular N-H?Cl and C-H?Cl hydrogen bonds.

Crystal structure studies of 4-ethyl-piperazin-1-ium 3,5-di-nitro-benzoate, 4-methyl-piperazin-1-ium 3,5-di-nitro-benzoate and 4-methyl-piperazin-1-ium 4-iodo-benzoate.

Project description:As part of our ongoing investigation on the chemical and biological properties of piperazinium salts, we synthesized three novel compounds: 1-ethyl-piperazinium 3,5-di-nitro-benzoate (I), 1-methyl-piperazinium 3,5-di-nitro-benzoate (II) and 1-methyl-piperazinium 4-iodo-benzoate (III). The crystal structures of these compounds are built up of organic layers formed by the strong connection between the mol-ecules by hydrogen bonds of type N-H⋯O. These layers are linked through N-H⋯O hydrogen bonds and C-H⋯O inter-actions or C-I⋯N halogen bonding, leading to the formation of a three-dimensional network.

Tetra-aqua-bis-(piperazin-1-ium)cobalt(II) bis-(sulfate) dihydrate.

Project description:In the centrosymmetric title compound, [Co(C4H11N2)2(H2O)4](SO4)2·2H2O, the Co(II) atom is coordinated in a distorted octa-hedral geometry by four water O atoms and two piperazinium N atoms. These four water O atoms define an equatorial plane with a maximum deviation of 0.0384 (1) Å while the two piperazinium N atoms complete the octa-hedron in the axial positions. Neighboring complex mol-ecules and sulfate anions are connected through an extensive network of N-H⋯O and O-H⋯O hydrogen bonds, which link the different chemical species into layers in the ab plane. Additional Owater-H⋯O hydrogen bonds involving the non-coordinating water mol-ecules and C-H⋯O inter-actions connect these layers into a three-dimensional supra-molecular structure.

Crystal structure of 1-(3-chloro-phen-yl)piperazin-1-ium picrate-picric acid (2/1).

Project description:The title salt {systematic name: bis-[1-(3-chloro-phen-yl)piperazinium 2,4,6-tri-nitro-phenolate]-picric acid (2/1)}, 2C10H14ClN2 (+)·2C6H5N3O7 (-)·C6H6N3O7, crystallized with two independent 1-(3-chloro-phen-yl)piperazinium cations, two picrate anions and a picric acid mol-ecule in the asymmetric unit. The six-membered piperazine ring in each cation adopts a slightly distorted chair conformation and contains a protonated N atom. In the picric acid mol-ecule, the mean planes of the nitro groups in the ortho-, meta-, and para-positions are twisted from the benzene ring by 31.5?(3), 7.7?(1), and 3.8?(2)°, respectively. In the anions, the dihedral angles between the benzene ring and the ortho-, meta-, and para-nitro groups are 36.7?(1), 5.0?(6), 4.8?(2)°, and 34.4?(9), 15.3?(8), 4.5?(1)°, respectively. The nitro group in one anion is disordered and was modeled with two sites for one O atom with an occupancy ratio of 0.627?(7):0.373?(7). In the crystal, the picric acid mol-ecule inter-acts with the picrate anion through a trifurcated O-H?O four-centre hydrogen bond involving an intra-molecular O-H?O hydrogen bond and a weak C-H?O inter-action. Weak inter-molecular C-H?O inter-actions are responsible for the formation of cation-anion-cation trimers resulting in a chain along [010]. In addition, weak C-H?Cl and weak ?-? inter-actions [centroid-centroid distances of 3.532?(3), 3.756?(4) and 3.705?(3)?Å] are observed and contribute to the stability of the crystal packing.

2-Amino-4-meth-oxy-6-methyl-pyrimidin-1-ium picrate.

Project description:In the title salt, C(6)H(10)N(3)O(+)·C(6)H(2)N(3)O(7) (-), the dihedral angle between the mean planes of the benzene and pyridine rings is 3.1?(1)°. In the cation, the meth-oxy group is almost coplanar with the pyridine ring [C-O-C-N = -0.6?(2)°]. The p-nitro [C-C-N-O = -1.17?(19)°] and one o-nitro [C-C-N-O = 1.83?(19)°] group in the anion are essentially coplanar with the benzene ring. The other disordered o-nitro group containing the major occupancy [0.868?(6)] O atom is twisted -29.0?(2)° from the mean plane of the benzene ring. A bifurcated N-H?(O.O) hydrogen bond and weak C-H?O intermolecular inter-action between the cation and anion produce a network of infinite O-H?O-H?O-H chains along the c axis in the [101] plane which helps to establish crystal packing. Comparison to a DFT computational calculation indicates that significant conformational changes occur in the free state.
