The crystal structures of two donor-acceptor azobenzenes, viz., 2'-methyl-4'-diethylamino-4-nitroazobenzene and 2-cyano-4'-diethylamino-4-nitro azo-henzene have been solved using direct methods with R-factors of 8.0 and 5.4% obtained. The molecular geometries and solid state structures are compared with previously published structures. Crystal packing studies have been employed to examine both the important intermolecular interactions and subtle interatomic interactions which govern the solid state structural arrangement adopted. © 1993.
