The molecular structure of (2E)-1,4-bis(4-chlorophenyl)but-2-ene-1,4-dione (1) is composed of two p-chloro phenyl rings, each bonded on opposite ends to a near planar 1,4-trans enedione moiety [–C(= O)—CH=CH—(C=O)–]. (2E)-1,4-Bis(4-bromophenyl)but-2-ene-1,4-dione (2) has… Click to show full abstract
The molecular structure of (2E)-1,4-bis(4-chlorophenyl)but-2-ene-1,4-dione (1) is composed of two p-chloro phenyl rings, each bonded on opposite ends to a near planar 1,4-trans enedione moiety [–C(= O)—CH=CH—(C=O)–]. (2E)-1,4-Bis(4-bromophenyl)but-2-ene-1,4-dione (2) has a similar structure to (1), but with two p-bromo phenyl rings and a less planar enedione group. In the crystal, molecules of (1) exhibit C—Cl⋯Cl type I interactions, whereas molecules of (2) present C–Br⋯Br type II interactions.
