Crystal structure and Hirshfeld surface analysis of two (E)-N′-(para-substituted benzylidene) 4-chlorobenzenesulfonohydrazides

Abstract

The crystal structures of (E)-4-chloro-N′-(4-chloro­benzyl­idene)benzene­sulfono­hydrazide and (E)-4-chloro-N′-(4-nitro­benzyl­idene)benzene­sulfono­hydrazide have been studied to investigate the effect of substituents on the structural parameters. The two-dimensional fingerprint plots of these two p-substituted compounds indicate that in the 4-chloro-substituted compound, the largest contribution to the Hirshfeld surface comes from the H⋯H contacts (26.6%), in contrast to the 34.8% contribution of the O⋯H/H⋯O contacts in the 4-nitro-substituted compound.
