(E)-N′-(4-Ethoxybenzylidene)-4-hydroxybenzohydrazide dihydrate
The benzohydrazide mol-ecule of the title compound, C(16)H(16)N(2)O(3)·2H(2)O, exists in a trans conformation with respect to the C=N double bond. The central O=C-NH-N=C plane [r.m.s. deviation of 0.0165 (1) Å for the five non-H atoms] makes dihedral angles of 6.04 (8) and 2.38 (8)°, respectively, with the hy-droxy- and eth-oxy-substituted benzene rings. The dihedral angle between these benzene...
متن کامل(E)-N′-(4-Methoxybenzylidene)pyridine-3-carbohydrazide dihydrate
In the title compound, C14H13N3O2·2H2O, the hydrazone mol-ecule adopts an E conformation with respect to the C=N bond. The dihedral angle between the benzene and pyridine rings is 8.55 (10)°. The methyl-idene-hydrazide [-C(=O)-N-N=C-] fragment is essentially planar, with a maximum deviation of 0.0375 (13) Å. The mean planes of the benzene and pyridine rings make dihedral angles of 2.71 (14) and...
متن کاملN,N-Bis(4-chlorophenylsulfonyl)succinamide dihydrate
The asymmetric unit of the title compound, C(16)H(14)Cl(2)N(2)O(6)S(2)·2H(2)O, contains one half-mol-ecule of N,N-bis-(4-chloro-phenyl-sulfon-yl)succinamide, with a centre of symmetry at the mid-point of the central C-C bond, and one water mol-ecule. The succinamide mol-ecules are not directly connected via hydrogen bonds, but by hydrogen bonds via the water mol-ecules.
متن کاملCrystal structure of 4-bromo-2-[(E)-N-(2,2,6,6-tetramethylpiperidin-4-yl)carboximidoyl]phenol dihydrate
In the title hydrate, C16H23BrN2O·2H2O, the organic mol-ecule features a strong intra-molecular O-H⋯N hydrogen bond. The piperidine ring, in addition, adopts a chair conformation with the exocyclic C-N bond in an equatorial orientation. The water molecules of crystallization are disordered (each over two sets of sites with half occupancy. In the crystal, they associate into corrugated (100) she...
متن کامل(E)-1-(4-Nitrophenyl)-2-(4-{[(E)-2-(4-nitrophenyl)hydrazinylidene]methyl}benzylidene)hydrazine dihydrate
The 30 non-H atoms in title dihydrazine compound, C(20)H(16)N(6)O(4)·2H(2)O, are close to coplanar, the r.m.s. deviation for these atoms being 0.096 Å. The conformation about each of the C=N bonds is E, and the mol-ecule has non-crystallographic 2/m symmetry. The presence of O-H⋯O and N-H⋯O hydrogen bonding leads to a three-dimensional network in the crystal structure. A highly disordered solve...
