Краткое описание

Two azomethynes, namely, derivatives of 5-bromo- and 3-nitrosalicyl aldehydes and 2-morpholinoethylamine (HL1, Z = Br and HL2, Z = NO2; in HL1,2 R = CH2CH2N(CH2)4O) are synthesized and analyzed by IR spectroscopy and single crystal X-ray diffraction. A benzenoid (enolimine) tautomeric form (a hydrogen atom is located at an oxygen atom) occurs in HL1. The structure is stabilized by an intramolecular О1–Н1В…N1 hydrogen bond (О–H 0.87(4) Å, H…N 1.83(4) Å, O…N 2.586(4) Å, ОHN angle 143(4)°). The HL2 molecule crystallizes in the quinoidal (quinone amine) tautomeric form with the intramolecular N1–Н1…O2 hydrogen bond (N–H 0.87(2) Å, H…O 1.99(2) Å, O…N 2.659(2) Å, NHO angle 134(2)°).
