title: 2-Amino-6-{[(6-chloropyridin-3-yl)methyl](ethyl)amino}-1-methyl-5-nitro-4-phenyl-1,4-dihydro-pyridine-3-carbonitrile ethanol monosolvate.
abstract: In the title compound, C(21)H(21)ClN(6)O(2)·C(2)H(6)O, a member of the insecticidal active neonicotinoid group of compounds, the 1,4-dihydro-pyridine ring adopts a boat conformation. An intra-molecular C-H⋯O hydrogen bond occurs while the components are linked by an N-H⋯O interaction. The crystal packing is stablized by O-H⋯N hydrogen bonds and C-H⋯O interactions.
