(E)-4-[(4-Diethyl-amino-2-hy-droxy-benzyl-idene)amino]-benzoic acid.

ABSTRACT: In the title compound, C(18)H(20)N(2)O(3), a potential bidentate N,O-donor Schiff base ligand, the benzene rings are inclined at an angle of 12.25 (19)°. The mol-ecule has an E conformation about the C=N bond. One of the ethyl groups is disordered over two positions, with a refined site-occupancy ratio of 0.55 (1):0.45 (1). An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds link mol-ecules, forming inversion dimers with R(2) (2)(8) ring motifs.

5-[(E)-(2,6-Dichloro-benzyl-idene)amino]-2-hy-droxy-benzoic acid.

Project description:There are two geometrically different mol-ecules in the asymmetric unit of the title compound, C(14)H(9)Cl(2)NO(3). The 5-amino-2-hy-droxy-benzoic acid units [r.m.s. deviations of 0.0323 and 0.0414 Å] and 2,6-dichloro-benzaldehyde groups [r.m.s. deviations of 0.0285 and 0.0226 Å] are roughly planar and oriented at dihedral angles of 11.69 (13) and 83.12 (6)° in the two mol-ecules. An intra-molecular O-H⋯O hydrogen bond completes an S(6) ring motif in each mol-ecule. The two mol-ecules form dimers with each other through inter-molecular O-H⋯N and C-H⋯O hydrogen bonds, completing an R(2) (2)(8) ring motif. The dimers are inter-linked via inter-molecular O-H⋯N and C-H⋯O hydrogen bonds, forming polymeric sheets.

Project description:In the title compound, C(14)H(10)FNO(3), the dihedral angle between the two benzene rings is 32.66 (14)°. An S(6) ring motif is formed due to an intra-molecular O-H⋯O hydrogen bond between the hy-droxy and carbonyl groups. In the crystal, mol-ecules are consolidated into dimers with R(2) (2)(8) ring motifs by pairs of O-H⋯O hydrogen bonds.

These dimers are further connected by C-H⋯O inter-actions, forming a sheet in (104). There is also a C-H⋯π inter-action present involving neighbouring mol-ecules.
