Syntesis and Crystallographic Structure Studies of N-[5-Methylisoxazole amino-3-yl]-3,5-di-tert-butylsalicylaldimine

Abstract

N-[5-Methylisoxazole amino-3-yl]-3,5-di-tert-butylsalicylaldimine [C₁₉H₂₆N₂O₂] was synthesized by the reaction of 3,5-di-tert-butylhydroxybenzaldehyde in absolute ethanol and 3-amino-5-methylisoxale in ethanole. Its structure was determined by X-ray crystallography. It crystallized in the monoclinic system, space group P2₁/n, with lattice parameters a = 9.024(2)Å, b =22.592(10)Å, c = 9.782(3)Å, β = 116.548(2)°, Z = 4, μ = 0.601 mm^-1, s = 1.013, R = 0.054 and wR = 0.110 for 2949 observed reflections. The structures were solved by direct methods using the SHELX-97 program and refined on F². The compound has four intramoleculer and three intermolecular contacts.
