چکیده
THE STRUCTURE OF THE TITLE COMPOUND (COMMON NAME: amodiaquinium dichloride dihydrate), C(20)H(24)ClN(3)O(2) (+)·2Cl(-)·2H(2)O, was previously determined from powder diffraction data [Llinàs et al. (2006 ▶). Acta Cryst. E62, o4196-o4199]. It has now been refined from diffractometer data to a significantly higher precision. The dihedral angle between the quinoline and benzene rings is 54.57 (6)°. The central amino N atom inter-acts more strongly with the quinoline ring than with the benzene ring, as indicated by the shorter C-N bond length [1.341 (2) Å compared to 1.431 (2) Å]. In the crystal, mol-ecules are packed into a three-dimensional network/supra-molecular structure through hydrogen bonds between the amodiaquinium cations, chloride anions and water mol-ecules.

Redetermination of bis{(1S,2S,4S,5R)-2-[(R)-hydroxy(6-methoxy-4-quinolyl)methyl]-5-vinylquinuclidinium} sulfate dihydrate
The structure of the title compound, known as quinine sulfate dihydrate, 2C(20)H(25)N(2)O(2) (+)·SO(4) (2-)·2H(2)O, was previously reported by Mendel [Proc. K. Ned. Akad. Wet. (1955), 58, 132-134], but only the [010] projection was determined. Hence, we have redetermined its crystal structure at 100 K using three-dimensional data. The asymmetric unit consists of a quininium cation, viz. (R)-(6-...

The title compound, C(23)H(30)ClN(5)O(3) (2+)·2Cl(-)·0.5H(2)O, was synthesized by N-alkyl-ation of 1-({[5-(4-chloro-phen-yl)-2-furan-yl]methyl-ene}amino)-2,4-imidazolidinedione with 1-bromo-4-chloro-butane, and N-methyl-piperazine. In the crystal, the cations, anions and water mol-ecules are linked by O-H⋯Cl and N-H⋯Cl hydrogen bonds.

Six new titanocene compounds have been isolated and characterised. These compounds were synthesised from their fulvene precursors using Super Hydride (LiBEt3H) followed by transmetallation with titanium tetrachloride to yield the corresponding titanocene dichloride derivatives. These complexes are bis-[((1-methyl-3-diethylaminomethyl)indol-2-yl)methylcyclopentadienyl] titanium (IV) dichloride (...

The title compound, C(6)H(8)N(4)O(3)·2H(2)O, which crystallized as a dihydrate, has two almost planar segments viz. the pyrimidine ring and the C-N-C(=O)-C group [maxmum deviations of 0.020 (2) and 0.014 (2) Å, respectively], with a dihedral angle of 87.45°. In the crystal, the components are linked by O-H⋯O and N-H⋯O hydrogen bonds.
