title: A combinatorial chemistry approach to new materials for non-linear optics. II. 4-(Dimethylamino)cinnamaldehyde and a molecular complex of 4-methoxycinnamaldehyde with 2,4-dinitroaniline
abstract: The combinatorial chemistry approach has been used to synthesize an array of Schiff bases. The structures of five of these Schiff bases have been confirmed by X-ray analysis [Nesterov, Timofeeva, Borbulevych, Antipin & Clark (2000). Acta Cryst. C56, 971-975]. In two cases, the reaction conditions were not sufficient to obtain the products in question. In one case, a molecular complex, C(10)H(10)O(2).C(6)H(5)N(3)O(4), of the starting products 4-methoxycinnamaldehyde and 2,4-dinitroaniline was found. X-ray analysis revealed hydrogen-bond formation between the molecules of these reagents in the crystal. In the other case, X-ray analysis demonstrated that no chemical reaction occurred under the reaction conditions, and only one starting reagent, 4-(dimethylamino)cinnamaldehyde, C(11)H(13)NO, was found in the precipitate.
