2,2′-(Biphenyl-4,4′-diyldioxy)diacetic acidN,N-dimethylformamide solvate

Abstract

In the crystal struture of the title compound, C16H14O6·C3H7NO, the two crystallographically independent benzene rings are coplanar [dihedral angle = 1.00 (2)°]. The crystal structure is stabilized by O—H⋯O hydrogen bonds between the diacid and the solvate dimethylformamide mol­ecule, resulting in the formation of a zigzag chain structure extending parallel to [001].

“…Some crystal structures containing biphenyl moiety have been reported. The two benzene rings are usually nearly coplanar for the biphenyl compounds without 2-substituents (Ali et al, 2008;Cao, 2009;Margraf et al, 2009;Li et al, 2009;Charbonneau & Delugeard, 1977). But the title compound displays a twisted conformation with a dihedral angle of 47.51 (4)° between the phenyl and benzene planes.…”
