Dl-Tyrosinium chloride dihydrate.

ABSTRACT: In the title compound, C(9)H(12)NO(3) (+)·Cl(-)·2H(2)O, the cation has a protonated amino group resulting from proton transfer from chloridric acid. The structure displays double layers parallel to the [010] direction held together by N-H?O, N-H?Cl, O-H?O and O-H?Cl hydrogen bonds. These layers are stacked along the c axis at b = 1/2; within each layer, the tyrosinium cations are arranged in an alternating head-to-tail sequence, forming inversion dimers [R(2) (2)(10) motif]. The water mol-ecules allow for the construction of a three-dimensional hydrogen-bonded network formed by centrosymmetric R(6) (6)(28) and R(8) (8)(34) motifs.

In the title compound, C(9)H(12)NO(3) (+)·Cl(-)·2H(2)O, the cation has a protonated amino group resulting from proton transfer from chloridric acid. The structure displays double layers parallel to the [010] direction held together by N-H⋯O, N-H⋯Cl, O-H⋯O and O-H⋯Cl hydrogen bonds. These layers are stacked along the c axis at b = 1/2; within each layer, the tyrosinium cations are arranged in an alternating head-to-tail sequence, forming inversion dimers [R(2) (2)(10) motif].

Aqua-(1,10-phenanthroline-?N,N')(dl-threoninato-?N,O)copper(II) chloride dihydrate.

Project description:The asymmetric unit of the title compound, [Cu(C(4)H(8)NO(3))(C(12)H(8)N(2))(H(2)O)]Cl·2H(2)O, contains a complex cation, a chloride anion and two water mol-ecules. The Cu(II) ion has a distorted square-pyramidal coordination geometry formed by one bidentate phenanthroline ligand, one O,N-bidentate dl-threoninate ligand and one apical water mol-ecule. In the crystal structure, inter-molecular O-H?O, N-H?O, N-H?Cl and O-H?Cl hydrogen bonds link the components into layers. A single weak inter-molecular C-H?O inter-action connects these layers into a three-dimensional network.

Enrofloxacin hydro-chloride dihydrate.

Project description:The asymmetric unit of the title compound, C19H23FN3O3 (+)·Cl(-)·2H2O [systematic name: 4-(3-carb-oxy-1-cyclo-propyl-6-fluoro-4-oxo-1,4-di-hydro-quin-o-lin-7-yl)-1-ethyl-piperazin-1-ium chloride dihydrate], consists of two independent monocations of the protonated enrofloxacin, two chloride anions and four water mol-ecules. In the cations, the piperazinium rings adopt chair conformations and the dihedral angles between the cyclo-propyl ring and the 10-membered quinoline ring system are 56.55 (2) and 51.11 (2)°. An intra-molecular O-H⋯O hydrogen bond is observed in each cation. In the crystal, the components are connected via O-H⋯Cl, N-H⋯Cl and O-H⋯O hydrogen bonds, and a π-π inter-action between the benzene rings [centroid-centroid distance = 3.6726 (13) Å], resulting in a three-dimensional array.

8-Iodo-quinolinium chloride dihydrate.

Project description:The title compound, C(9)H(7)IN(+)·Cl(-)·2H(2)O, was obtained during the synthesis of 8-iodo-quinoline from 8-amino-quinoline using the Sandmeyer reaction. The 8-iodo-quinolinium ion is almost planar. Solvent water mol-ecules and chloride ions form a hydrogen-bonded chain along the c axis via O-H⋯Cl links. The 8-iodo-quinolinium ions, which are packed along the c axis with cationic aromatic π-π stacking (centroid-centroid distance = 3.624 Å), are linked to the chain via N-H⋯O hydrogen bonds.

2-Amino-4,6-dimethyl-pyridinium chloride dihydrate.

Project description:In the title hydrated mol-ecular salt, C(7)H(11)N(2) (+)·Cl(-)·2H(2)O, the pyridine N atom of the 2-amino-4,6-dimethyl-pyridine mol-ecule is protonated. The cation is essentially planar, with a maximum deviation of 0.006?(2)?Å. In the crystal, the components are linked by N-H?O, N-H?Cl and O-H?Cl hydrogen bonds, thereby forming sheets lying parallel to (100). The crystal structure is further stabilized by aromatic ?-? stacking inter-actions between the pyridinium rings [centroid-centroid distance = 3.4789?(9)?Å].

3-Hydr-oxy-1,2,3,9-tetra-hydro-pyrrolo[2,1-b]quinazolin-4-ium chloride dihydrate: (+)-vasicinol hydro-chloride dihydrate from Peganum harmala L.

Project description:The title compound, C(11)H(13)N(2)O(+)·Cl(-)·2H(2)O, the dihydrate of (+)-vasicinol hydro-chloride, is a pyrrolidinoquinazoline alkaloid. It was isolated from the ethyl acetate fraction of the leaves of Peganum harmala L. The pyrrolidine ring has an envelope conformation with the C atom at position 2 acting as the flap and the C atom at position 3, carrying the hydroxyl substituent, has an S configuration. The absolute configuration was determined as a result of the anomalous scattering of the Cl atom. In the crystal structure, mol-ecules stack along the a axis, connected to one another via inter-molecular O-H?Cl and N-H?Cl hydrogen bonds, forming approximately triangular-shaped R(2) (1)(7) rings, and O-H?Cl and O-H?O hydrogen bonds, forming penta-gonal-shaped R(5) (4)(10) rings. The overall effect is a ribbon-like arrangement running parallel to the a axis.
