Аннотация
Two new hydrazone compounds C14H10I2N2O3·CH3OH (1) and C19H16N2O3·2CH3OH (2) are synthesized by the condensation reactions of the equimolar quantities of 4-hydroxybenzohydrazide with 3,5-diiodo-2-hydroxybenzaldehyde and 2-methoxynaphth-1-yl-methylene respectively in methanol solutions. Compound 1 consists of a hydrazone molecule and a methanol molecule of crystallization, and compound 2 consists of a hydrazone molecule and two methanol molecules of crystallization. Both compounds are characterized by elemental analysis, IR spectra, and single crystal X-ray diffraction. As expected, each hydrazone molecule adopts an E configuration about the C=N double bond. In the crystal structures of both compounds, the hydrazone and methanol molecules are linked through intermolecular N-H⋯O and O-H⋯O hydrogen bonds, forming layers along the bc direction.
