(E)-N'-(4-Pyridylmethyl-ene)-4-(8-quinol-yl-oxy)butanohydrazide 0.25-hydrate.

ABSTRACT: The asymmetric unit of the title compound, C(19)H(18)N(4)O(2)·0.25H(2)O, contains two organic mol-ecules and a solvent water mol-ecule with 50% occupancy. The two molecules differ in their conformations: in one mol-ecule it is (+)gauche-trans-trans-(+)gauche-trans, whereas in the other it is (-)gauche-trans-trans-(-)gauche-trans. The dihedral angles between the pyridine ring and the quinoline ring system are 67.4?(3) and 68.0?(2)°. Mol-ecules are linked into a supra-molecular two-dimensional array via N-H?N hydrogen bonds, with each partially occupied water mol-ecule connected via an O-H?O hydrogen bond. C-H?O inter-actions are also present.

2-Amino-5-chloro-pyridinium (Z)-3-carb-oxy-prop-2-enoate 0.25-hydrate.

Project description:In the title hydrated salt, C(5)H(6)ClN(2) (+)·C(4)H(3)O(4) (-)·0.25H(2)O, the water O atom lies on a twofold axis with 0.25 occupancy. The 2-amino-5-chloro-pyridinium cation is almost planar, with a maximum deviation of 0.015?(3)?Å. In the hydrogen malate anion, an intra-molecular O-H?O hydrogen bond generates an S(7) ring and results in a folded conformation. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are further connected via O-H?O, N-H?O and C-H?O hydrogen bonds, forming layers parallel to the ab plane which stack down the c axis.

The geometry about the Pd atom is distorted square-planar. The pyrazole rings are almost perpendicular, forming a dihedral angle of 86.6?(6)° to each other, to mitigate steric conflict between their methyl groups.

4-(3-Methyl-anilino)-N-[N-(1-methyl-ethyl)carbamo-yl]pyridinium-3-sulfon-amidate (torasemide) methanol 0.25-solvate 0.25-hydrate.

Project description:The title compound, C(16)H(20)N(4)O(3)S·0.25CH(4)O·0.25H(2)O, is a hydrate/methanol solvate of torasemide, a diuretic drug used in the treatment of hypertension. The asymmetric unit contains two torasemide mol-ecules and half-occupied methanol and water mol-ecules. It is isomorphous with the previously reported nonsolvated T-II form of torasemide. The water mol-ecules contribute to the stability of the structure by participating in an extensive system of O-H?O hydrogen bonds; N-H?N and N-H?O hydrogen bonds are also present. Both asymmetric mol-ecules of torasemide form inversion dimers in the crystal.
