Diethyl 2,2′-bis(hydroxyimino)-3,3′-(hydrazinediylidene)dibutanoate

Abstract

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.002 Å; R factor = 0.039; wR factor = 0.110; data-to-parameter ratio = 13.4.Each molecule of the title compound, C 12 H 18 N 4 O 6 , is located on an inversion centre at the mid-point of the central N-N bond. The azo groups C N of the Schiff base group have an E conformation and the azo groups in the oxime C N-O groups have a Z conformation. O-HÁ Á ÁO hydrogen bonds link neighbouring molecules into infinite monolayers perpendicular to the a axis. Related literature
