Specific Features of the Molecular Structure of A New 3-(Benzo[d]Oxazole-2-Yl)- 1-(2-(1,3,3-Trimethylindoline-2-Ylidene) Ethylidene)Naphthalene-2(1H)-One Zinc Chloride Complex

Abstract

X-ray diffraction is used to determine the structure of a new 3-(benzo[d]oxazole-2-yl)-1-(2-(1,3,3- trimethylindoline-2-ylidene)ethylidene)naphthalene-2(1H)-one zinc chloride complex 1. It is demonstrated that the ligand molecule in complex 1 has a trans–trans–cis conformation in which the indoline nitrogen atom is oriented in the same direction as the chelate ring, which could promote an additional coordination with the complexing atom.
