4-nitrobenzaldoxime and cynnamaldoxime structures

Бесплатный доступ

The structures of 4-nitrobenzaldoxime (1) and cynnamaldoxime (2) have been determined by X-ray diffraction analysis. In the oxime molecules the distances C=N, N-O have the usual values for oximes (1.267(3), 1.403(2) Å for 1 and 1.278(4), 1.395(3) Å for 2a, 1.284(4), 1.384(3) Å for 2b). In crystals the oximes are observed as dimers: two oxime 1 molecules are interconnected by two hydrogen bonds N(1A)…H(1B) (2.12 Å), two oxime 2 molecules are interconnected by the single hydrogen bond N(1A)…H(1B) (1.66 Å).
