چکیده
In the racemic hydro-chloride salt of the title ester, C(19)H(22)Cl(2)NO(2) (+)·Cl(-), the penta-noic acid chain shows a mixture of trans and gauche orientations to give an overall helical conformation. The dihedral angle between the two aromatic rings is 26.11 (10)°. The charged secondary amine function participates in two N-H⋯Cl hydrogen bonds.

The title compound, C(34)H(36)Cl(2)O(7), is a by-product from the reaction of 4-chloro-benzyl-zinc chloride with 3,4,5-trimeth-oxy-benzaldehyde. In each of the two 1,2-diphenyl-ethyl moieties, the two benzene rings are arranged in a trans conformation and make C(ar)-C-C-C(ar) torsion angles of 163.64 (19) and 174.43 (18)°. The crystal structure is stabilized by van der Waals inter-actions only.
