N′-(2-Methyl-3-phenylallylidene)nicotinohydrazide monohydrate
The asymmetric unit of the title compound, C(16)H(15)N(3)O·H(2)O, contains an N'-(2-methyl-3-phenyl-allyl-idene)nicotino-hydra-zide mol-ecule and a water solvent mol-ecule. The dihedral angle between the pyridine ring and the phenyl ring is 47.26 (5)°. Inter-molecular O-H⋯N, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds are found in the crystal structure. Furthermore, C-H⋯π inter-actions involving the ...

In the title ionic liquid salt hydrate, C(18)H(35)N(2) (+)·Br(-)·H(2)O, the side chain in the cation has an extended conformation. The crystal structure is stabilized primarily by O-H⋯Br hydrogen bonds. C-H⋯O and C-H⋯Br inter-actions are also present.
متن کاملMethyl 4-isonicotinamidobenzoate monohydrate
The title compound, C(14)H(12)N(2)O(3)·H(2)O, synthesized by the reaction of methyl 4-amino-benzoate with isonicotinoyl chloride hydro-chloride, is relatively planar, with the pyridine ring being inclined by 7.46 (7)° to the benzene ring. In the crystal, the methyl 4-isonicotinamido-benzoate mol-ecules are inter-linked by water mol-ecules via N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, leading to th...
متن کامل3-Methyl-1,2,4-triazolo[3,4-a]phthalazine monohydrate
In the crystal structure of the title compound, C(10)H(8)N(4)·H(2)O, the organic mol-ecules are approximately planar [maximum deviation from the least-squares plane = 0.041 (2) Å]. Two mol-ecules are connected by two water mol-ecules via O-H⋯N hydrogen bonding into dimers, which are located around centres of inversion. In the crystal, mol-ecules are stacked in the a-axis direction, with mean di...
متن کامل5-Cyclohexyl-4-methyl-1H-pyrazol-3(2H)-one monohydrate
In the title compound, C(10)H(16)N(2)O·H(2)O, the cyclo-hexane ring is in a chair conformation and its least-squares plane makes a dihedral angle of 53.68 (5)° with the approximately planar pyrazole ring [maximum deviation = 0.034 (1) Å]. Pairs of inter-molecular N-H⋯O hydrogen bonds form inversion dimers between neighbouring pyrazolone mol-ecules, generating R(2) (2)(8) ring motifs. The pyrazo...
