Crystallographic study of two monoazo disperse dyes with a D-pi-A system

Two azo disperse dyes, 2,6-dichoro-4-nitro-4,4-N-cyanoethyl-N-benzyl-azobenzene (D1) and 3-(3-methyl-4-N-ethyl-N-benzyl-phenyldiazenyl)-5-nitro-2,1-benzisothiazole (D2), were synthesised and characterised. The crystal morphologies and single crystal structures were measured. The various packing and supramolecular interactions were described. D1 formed stellate crystals. The two benzene rings bilateral to the azo unit were not coplanar. Their dihedral angle was 75.72 degrees. They were linked by the azo unit and were twisted. The coupling-component N-substituted benzyl and benzene rings were not coplanar. The chemical structure was not the typical azo structure. A dimeric packing mode was formed between adjacent molecules in a head-to-head and tail-to-tail manner. One molecule was inserted between two dimeric molecules in a head-to-tail manner. D2 formed globe crystals. The isothiazole and benzene rings of the azo unit were coplanar, with the typical – conjugated structure. The benzene rings of the azo unit and the coupling-component N-substituted benzyl were vertical. Their torsion angle was 179.9 degrees.

The molecular packing in 6 is influenced by C-H center dot center dot center dot X (X = N, O) hydrogen bonds and pi center dot center dot center dot pi interactions of the pairs of isothiazolopyridine rings belonging to inversion related molecules. The crystal structure of 7 contains the net of O-H center dot center dot center dot N and C-H center dot center dot center dot O intermolecular hydrogen bonds. Moreover, isothiazole and pyridine rings show significant stacking with the shortest pi center dot center dot center dot pi distances of 3.453 angstrom. The conformations of the molecules 6 and 7 were compared with those observed in the crystals of related analgesic 4-arylpiperazine (2, 3) and 4-arylpiperidine (4, 5) derivatives of isothiazolopyridine of Mannich base type. Additionally, the computational investigations using semi-empirical AMI and RHF/6-31G** ab initio methods are performed within series 2-7 in order to find correlation between geometrical and electronic parameters of the molecules and their analgesic action. Results of the theoretical calculations show that the charge distribution on the piperazine N atoms is correlated with conformation of the (4-arylpiperazin-1-yl)methyl side chain and analgesic action of isothiazolopyridines analyzed.
