Abstract
Terephthalaldehyde forms monoclinic crystals, space group P21/a, a = 12.698(6), b = 3.845(2), c = 14.764(3) Å, β = 116.53(3)°, Z = 4, V = 645(1) Å3, and Dx = 1.381(2) g cm−3. There are two independent molecules, each located at a center of symmetry and approximately related to each other by pseudo-symmetry. In both molecules the rings are planar within experimental error. In one molecule the CHO groups are twisted out of the plane of the ring by 1.3(1)°, in the other by 0.6(1)°. Weak C–H···O hydrogen bonds occur at both independent aldehyde hydrogen atoms.
