Crystal structure studies of 4-ethylpiperazin-1-ium 3,5-dinitrobenzoate, 4-methylpiperazin-1-ium 3,5-dinitrobenzoate and 4-methylpiperazin-1-ium 4-iodobenzoate

ABSTRACT: Three novel piperazinium salts are described. Their crystal structure is based on layers formed by hydrogen bonding, halogen bonding and other weak interactions. One exhibits an asymmetric unit containing a 1-ethylpiperazinium cation and a 3,5-dinitrobenzoate anion while the other two salts have asymmetric units containing 1-methylpiperazinium as a common cation and a 3,5-dinitrobenzoate anion or a 4-iodobenzoate anion. As part of our ongoing investigation on the chemical and biological properties of piperazinium salts, we synthesized three novel compounds: 1-ethylpiperazinium 3,5-dinitrobenzoate (I), 1-methylpiperazinium 3,5-dinitrobenzoate (II) and 1-methylpiperazinium 4-iodobenzoate (III). The crystal structures of these compounds are built up of organic layers formed by the strong connection between the molecules by hydrogen bonds of type N—H⋯O. These layers are linked through N—H⋯O hydrogen bonds and C—H⋯O interactions or C—I⋯N halogen bonding, leading to the formation of a three-dimensional network.

Project description:In the cation of the title salt, C9H13N2O2 (+)·C7H3N2O6 (-), the piperazine ring adopts a slightly distorted chair conformation. Twofold rotational disorder is exhibited by the furan ring in a 0.430?(4):0.570?(4) ratio. In the crystal, N-H?O hydrogen bonds link the ions into chains along [010]. Additional weak C-H?O inter-actions are observed, leading to a supra-molecular layer parallel to (011).

Crystal structure of ebastinium 3,5-di-nitro-benzoate.

Project description:Ebastine, 4-(benzhydr-yloxy)-1-[4-(4-tert-butyl-phen-yl)-4-oxobut-yl]piperidine, reacts with 3,5-di-nitro-benzoic acid in methanol solution to give the title 1:1 salt, ebastinium 3,5-di-nitro-benzoate, C32H40NO2+·C7H3N2O6-. In the cation, the disubstituted aryl ring exhibits orientational disorder over two sets of atomic sites having occupancies 0.706 (4) and 0.294 (6), with a dihedral angle of 41.2 (5)° between the two orientations: the bulky Ph2CH-O- substituent occupies an axial site on the piperidine ring. The two ions in the selected asymmetric unit are linked by a nearly linear N-H⋯O hydrogen bond and this, in combination with two C-H⋯O hydrogen bonds, links the ions into complex sheets.

Syntheses and crystal structures of 4-(4-nitro-phen-yl)piperazin-1-ium benzoate monohydrate and 4-(4-nitro-phen-yl)piperazin-1-ium 2-carb-oxy-4,6-di-nitro-phenolate.

Project description:Crystal structures are reported for two mol-ecular salts containing the 4-(4-nitro-phen-yl)piperazin-1-ium cation. Co-crystallization from methanol/ethyl acetate solution of N-(4-nitro-phen-yl)piperazine with benzoic acid gives the benzoate salt, which crystallizes as a monohydrate, C10H14N3O2·C7H5O2·H2O, (I), and similar co-crystallization with 3,5-di-nitro-salicylic acid yields the 2-carb-oxy-4,6-di-nitro-phenolate salt, C10H14N3O2·C7H3N2O7, (II). In the structure of (I), a combination of O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds links the components into sheets, while in the structure of (II), the supra-molecular assembly, generated by hydrogen bonds of the same types as in (I), is three dimensional. Comparisons are made with the structures of some related compounds.

Crystal structures of methyl 3,5-di-bromo-4-cyano-benzoate and methyl 3,5-di-bromo-4-iso-cyano-benzoate.

Project description:The title crystals, C9H5Br2NO2, are the first reported 2,6-dihalophenyl cyanide-isocyanide pair that have neither three- nor two-dimensional isomorphism. Both crystals contain contacts between the carbonyl O atom and a Br atom. In the crystal of the cyanide, R22(10) inversion dimers form based on C≡N⋯Br contacts, a common packing feature in this series of crystals. In the isocyanide, the corresponding N≡C⋯Br contacts are not observed. Instead, the iso-cyano C atom forms contacts with the meth-oxy C atom. RNC was refined as a two-component pseudo-merohedral twin.

Crystal-structure studies of 4-phenyl-piperazin-1-ium 4-eth-oxy-benzoate monohydrate, 4-phenyl-piperazin-1-ium 4-meth-oxy-benzoate monohydrate, 4-phenyl-piperazin-1-ium 4-methyl-benzoate monohydrate and 4-phenyl-piperazin-1-ium tri-fluoro-acetate 0.12-hydrate.

Project description:In this study, four new piperazinium salts, namely, 4-phenyl-piperazin-1-ium 4-eth-oxy-benzoate monohydrate, C9H9O3·C10H15N2·H2O (I); 4-phenyl-piperazin-1-ium 4-meth-oxy-benzoate monohydrate, C10H15N2·C8H7O3·H2O (II); 4-phenyl-piperazin-1-ium 4-methyl-benzoate monohydrate, C10H15N2·C8H7O2·H2O (III); and 4-phenyl-piperazin-1-ium tri-fluoro-acetate 0.12 hydrate, C10H15N2·C2F3O2·0.12H2O (IV), have been synthesized. The single-crystal structures of these compounds reveal that all of them crystallize in the triclinic P space group and the crystal packing of (I)-(III) is built up of ribbons formed by a combination of hydrogen bonds of type N-H⋯O, O-H⋯O and other weak inter-actions of type C-H⋯O and C-H⋯π, leading to a three-dimensional network. In the crystal of (IV), the cations and the anions are connected by C-H⋯O, N-H⋯O and C-H⋯F hydrogen bonds and by C-H⋯π inter-actions, forming sheets which in turn inter-act to maintain the crystal structure by linking through the oxygen atoms of water mol-ecules and van der Waals inter-actions, giving the whole structure.

Crystal structure of 4-hy-droxy-pyridin-1-ium 3,5-di-carb-oxy-benzoate.

Project description:The structure of the title salt, C5H6NO(+)·C9H5O6 (-), (I), shows that 4-hy-droxy-pyridine has abstracted an H atom from benzene-1,3,5-tri-carb-oxy-lic acid, yielding a pyridinium cation and carboxyl-ate anion. The two ions form an extensive three-dimensional hydrogen-bonded network throughout the crystal. The hydrogen bonds that comprise the core of the network are considered strong, with O-H⋯O and N-H⋯O donor-to-acceptor distances ranging from 2.533 (2) to 2.700 (2) Å. Packing is further enhanced by π-stacking of the cations and anions with like species [centroid-centroid distance = 3.6206 (13) Å].

Crystal structure of 3,5-di-methyl-phenyl 2-nitro-benzene-sulfonate.

Project description:The title compound, C14H13NO5S, was synthesized via a nucleophilic substitution reaction between 3,5-di-methyl-phenol and 2-nitro-benzene-sulfonyl chloride. The aromatic rings attached to the SO3 group are oriented in a gauche fashion around the ester S-O bond, with a C-S-O-C torsion angle of 84.68 (11)°. The mol-ecules form centrosymmetric dimers via π-π stacking inter-actions between 3,5-di-methyl-phenyl groups (centroid-centroid distance = 3.709 Å). An inter-molecular S=O⋯N inter-action between the sulfonyl and nitro groups, with an O⋯N distance of 2.9840 (18) Å, organizes the dimers into columns extending along [011]. These columns are further assembled into (111) layers through C-H⋯O inter-actions.

Syntheses and crystal structures of 4-(4-meth-oxy-phen-yl)piperazin-1-ium 4-methyl-benzoate monohydrate and bis-[4-(4-meth-oxy-phen-yl)piperazin-1-ium] benzene-1,2-di-carboxyl-ate.

Project description:Co-crystallization of N-(4-meth-oxy-phen-yl)piperazine with 4-methyl-benzoic acid and with benzene-1,2-di-carb-oxy-lic acid yields the salts 4-(4-meth-oxy-phen-yl)piperazin-1-ium 4-methyl-benzoate monohydrate, C11H17N2O+·C8H7O2 -·H2O (I), and bis-[4-(4-meth-oxy-phen-yl)piperazin-1-ium] benzene-1,2-di-carboxyl-ate, 2C11H17N2O+·C8H4O4 2- (II). These salts both crystallize with Z' = 2, in space groups P and Pna21, respectively. In compound (I), a combination of four O-H⋯O, four N-H⋯O, one C-H⋯O and one C-H⋯π(arene) hydrogen bonds link the six independent components into complex sheets, within which the two piperazine rings, the two anions, and the two water mol-ecules are related by an approximate, non-crystallographic translation along the b-axis direction. In compound (II), sheets containing R 4 4(18) and R 10 12(38) rings are formed by the combined action of eight independent N-H⋯O hydrogen bonds. Comparisons are made with the structures of some related compounds.

4-[Bis(4-fluorophenyl)methyl]piperazin-1-ium 2-(2-phenylethyl)benzoate.

Project description:The asymmetric unit of the title salt, C(17)H(19)F(2)N(2) (+.)C(15)H(13)O(2) (-), derived from a 1,4-diaza-cyclo-hexane derivative and a carb-oxy-lic acid, contains two formula units. The cation is protonated at the secondary amine functionality. The six-membered heterocycles adopt chair conformations. The fluorophenyl rings in the two cations make dihedral angles of 77.21?(19) and 78.8?(2)° while the aromatic rings in the anions enclose angles of 69.5?(2) and 69.9?(2)°. In the crystal, classical N-H?O hydrogen bonds as well as C-H?F and C-H?O contacts connect the entities into layers parallel to ac.

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.
