Crystal structure of (E)-1-(2-hydroxy-3-{[2-hydroxybenzylidene]amino}phenyl)ethan-1-one, C₁₅H₁₃NO₃

Abstract

C 15 H 13 NO 3 , monoclinic, P2 1 /c (no. 14) a = 7.5158(6) Å, CCDC no.: 1531176The crystal structure is shown in the figure. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters. Source of materialAll chemicals were used as received. A solution of salicylaldehyde (810 mg, 6.62 mmol) in ethanol (25 mL) was added to the ethanolic solution (25 mL) of 3-amino-2-hydroxyacetophenone (1000 mg, 6.62 mmol). The solution was stirred with reflux at 328 K for 12 h, after which the mixture was filtered and the filtrate was washed successively with ethanol and hexane in the ratio 1:4, respectively. Then the product was dried using a vacuum desiccator on calcium chloride which resulted in a clear light brown powder
