Abstract

CCDC no.: 1526218The asymmetric unit of the title crystal structure is shown in the gure. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters. Source of materialThe title compound was synthesized according to a reported procedure [1]. A mixture of 3,5-cyclohexanedione (10 mmol), 3,5-dichlorobenzaldehyde (10 mmol), malononitrile (10 mmol) and 4-(dimethylamino)pyridine (DMAP) (1 mmol) in ethanol (100 mL) was re uxed for 2-3 h and then cooled to room temperature. After ltering the precipitates,
