Crystal structure of (2E)-2-methoxyimino-2-{2-[(2-methylphenoxy)methyl]phenyl}-N′-(4-nitrobenzylidene)ethanohydrazide

Abstract

The title compound crystallizes with the two mol­ecules in the asymmetric unit (Z′ = 2) oriented almost perpendicular to each other [dihedral angle between the central core of each mol­ecule = 77.95 (3)°]. The two mol­ecules exhibit similar conformations with an extended structure and are linked by bifurcated hydrogen bonds into a ribbon along the a-axis direction.

(Z)-N′-[(E)-4-Methoxybenzylidene]-2-(methoxyimino)-2-{2-[(2-methylphenoxy)methyl]phenyl}acetohydrazide

“…As these types of compounds are easily metabolized in nature as well as in living systems, their modifications are of importance in order to improve their activity (Balba, 2007). In order to increase the activity of the starting compounds (Kant et al 2012), it is necessary to modify the basic skeleton and initiate a structural investigation of different derivatives of kresoxim-methyl derivatives and in that light we previously reported the crystal structure of a related derivative, (2E)-2-methoxyimino-2-{2-[(2-methylphenoxy)methyl]phenyl}-N 0 -(4-nitrobenzylidene)ethanohydrazide (Shripanavar & Butcher, 2015). This paper is a continuation in this series.…”

“…A search for related structures resulted in two close matches. The first is the parent azide from which the current structure is derived (Chopra et al, 2004) and the second is that with a nitro substituent instead of a methoxy substituent on the phenyl ring (CSD refcode JUFCIY; Shripanavar & Butcher, 2015). The major difference between the methoxy and nitro derivatives lies in the dihedral angles between the central benzene rings and the o-tolyl groups at the other end of the molecule: in the current structure these are 82.1 (1) and 86.1 (1) while in JUFCIY the equivalent angles are 46.98 (5) and 48.23 (4) .…”
