3-(4-Chlorophenyl)-4-phenylthiosydnone

Abstract

In the structure of C14H9ClN2O2S [systematic name: 3-(4-chlorophenyl)-4-(phenylsulfanyl)-1,2,3λ5-oxadiazol-3-ylium-5-olate], the central sydnone ring is inclined at angles of 67.49 (10)° to the phenyl ring of the thiophenyl substituent and 52.61 (10)° to the chlorophenyl ring. The compound crystallizes utilizing a network of weak S and Cl-based hydrogen bonds, together with S...π, O...π and C—H...π interactions, forming a three-dimensional structure. In spite of having three planar rings, no π–π interactions are found.
