(Z)-Ethyl 2-hydroxy­imino-2-(4-nitro­benz­yl)ethanoate

The title mol­ecule, C(11)H(10)N(2)O(6), has a Z conformation about the C=N bond of the oxime unit. There are significant twists from planarity throughout the mol­ecule, the most significant being between the hydroxy­imino and ester groups which are effectively orthogonal with an N—C—C—O(carbon­yl)...

Descripción
Sumario:The title mol­ecule, C(11)H(10)N(2)O(6), has a Z conformation about the C=N bond of the oxime unit. There are significant twists from planarity throughout the mol­ecule, the most significant being between the hydroxy­imino and ester groups which are effectively orthogonal with an N—C—C—O(carbon­yl) torsion angle of 91.4 (2)°. The crystal packing features oxime–benzoyl O—H⋯O contacts that lead to chains along [010] and C—H⋯O interactions also occur.
