3,5-Dimethyl-1-(2-pyridylcarbon-yl)-5-[(2-pyridylcarbon-yl)hydrazino]-2-pyrazoline methanol hemisolvate.

ABSTRACT: The title compound, C(17)H(18)N(6)O(2)·0.5CH(3)OH, exists in the double keto form and adopts a highly puckered geometry, stabilized by intra-molecular N-H?O and N-H?N hydrogen bonds. Inter-molecular N-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid separation = 3.654?(1)?Å] assemble the mol-ecules into chains running in the [111] direction. The methanol solvent mol-ecule is disordered over two sites related by inversion and forms a bifurcated O-H?(N,O) hydrogen bond.

The title compound, C(17)H(18)N(6)O(2)·0.5CH(3)OH, exists in the double keto form and adopts a highly puckered geometry, stabilized by intra-molecular N-H⋯O and N-H⋯N hydrogen bonds. Inter-molecular N-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-centroid separation = 3.654 (1) Å] assemble the mol-ecules into chains running in the [111] direction. The methanol solvent mol-ecule is disordered over two sites related by inversion and forms a bifurcated O-H⋯(N,O) hydrogen bond. ...[more]

Project description:In the title complex, [Gd(C(11)H(10)N(3)O(2))(3)]·0.5CH(4)O·2.5H(2)O, the Gd atom is coordinated by six N atoms and three O atoms derived from three tridentate monoanionic 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The mol-ecules are linked together via hydrogen bonds involving the solvent water and methanol mol-ecules.

Project description:In the title mol-ecule, C(16)H(16)N(2)O(3), intra-molecular O-H?O hydrogen bonds influence the mol-ecular conformation. Inter-molecular O-H?O hydrogen bonds [O?O = 2.922?(2)?Å] link the mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H?O inter-actions assemble these dimers into layers parallel to the bc plane.

2,4-Bis(4-chloro-benzo-yl)-1-(4-chloro-phen-yl)-3,5-di-2-thienylcyclo-hexa-nol methanol hemisolvate.

Project description:The title compound, C(34)H(25)Cl(3)O(3)S(2)·0.5CH(3)OH, was synthesized by the reaction of thio-phene-2-carbaldehyde with acetophenone and NaOH under solvent-free conditions, using tetra-butylammonium bromide as a phase-transfer catalyst. The central six-membered ring adopts a chair conformation with the bulky thio-phene, 4-chloro-phenyl and 4-chloro-benzoyl substituents in equatorial positions. The hydroxyl group is in an axial position and forms an intra-molecular O-H⋯O hydrogen bond to the carbonyl group of an adjacent 4-chloro-benzoyl substituent. The methanol solvent mol-ecules are disordered equally over two positions within one-dimensional channels, with site occupancy factors of 0.25.

Project description:The title compound, C(16)H(16)N(4)O(2)S, crystallizes with two symmetry-independent half-mol-ecules in the asymmetric unit. All non-H atoms in each molecule lie in a crystallographic mirror plane. The mol-ecules form sheets in the ac plane, which then form stacks along the b axis. The sheets are connected via π-π stacking inter-actions [centroid-centroid distance between pyrazolato rings = 3.6949 (8) Å].

Project description:In the crystal structure of the title solvated salt, C(16)H(19)N(2) (+)·C(8)H(5)O(7)S(-)·CH(3)OH, the anions and the methanol solvent mol-ecules are linked by O-H⋯O hydrogen bonds.
