A new organic crystal with a noncentrosymmetric structure is developed, and its structural, thermal, linear and nonlinear optical properties are reported.
The title molecular salts are stilbazole, or 4-styrylpyridine, derivatives in which the cation has a methyl group attached to the pyridine ring N atom and a diethyl amine group attached to the benzene ring. In salt (I), the cadmium atom of the [CdI4]2− dianion is located on a twofold rotation axis and the compound crystallizes with one cation in the asymmetric unit. In salt(II), the anion consists of a 4-methoxybenzenesulfonate ion, and it crystallizes as a monohydrate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
