Sažetak
Two structural isomers of 5-methoxysalicylaldimine Schiff-bases ; N-(o-hydroxyphenyl)-5-methoxysalicylaldimine, [(Sal-o-OH-ph)H], and N-(m-hydroxyphenyl)-5-methoxysalicylaldimine, [(Sal-m-OH-ph)H], have been prepared and characterized in the solid state by means of the single crystal X-ray diffractometry at 298 and 200 K, and also by IR spectroscopy. Two structures, which are different only in the position of the N-substituent phenyl ring hydroxy group, are characterized by different tautomeric forms, i.e. ortho- and meta-hydroxy derivates exist as the N-H˙˙˙O and O-H˙˙˙N tautomers, respectively.
