Abstract

The title Schiff base compound, C(14)H(12)BrClN(2)O, exists in an E configuration with respect to the central C=N double bond. The amino group adopts a pyramidal configuration. The dihedral angle between the two benzene rings is 76.88 (10)° and an intra-molecular O-H⋯N hydrogen bond forms a six-membered ring, generating an S(6) ring motif. In the crystal structure, mol-ecules are linked into chains along [010] via N-H⋯O hydrogen bonds. The presence of π-π inter-actions [centroid-centroid distance = 3.6244 (12) Å] further stabilizes the crystal structure.

摘要

席夫碱化合物C(14)H(12)BrClN(2)O相对于中心C=N双键以E构型存在。氨基呈棱锥形构型。两个苯环之间的二面角为76.88 (10)°,分子内O-H⋯N氢键形成一个六元环,产生S(6)环模式。在晶体结构中,分子通过N-H⋯O氢键沿[010]方向连接成链。π-π相互作用的存在[质心-质心距离 = 3.6244 (12) Å]进一步稳定了晶体结构。
