Bis[4-hy-droxy-3,5-dimeth-oxy-benzalde-hyde (2,4-dinitro-phen-yl)hydrazone] N,N-dimethyl-formamide disolvate
Abstract:
In the title compound, 2C(15)H(14)N(4)O(7)·2C(3)H(7)NO·H(2)O, the hydrazone mol-ecules are roughly planar, with the two benzene rings twisted slightly relative to each other by dihedral angle of 6.04 (11) and 7.75 (11)° in the two mol-ecules. The water mol-ecule is linked to the Schiff base mol-ecule by an O-H⋯O hydrogen bond. Intra-molecular N-H⋯O hydrogen bonds occur. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.

Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
