Hydrothermal synthesis, crystal structure and third-order non-linear optical property of a novel three-dimensional supramolecular network compound [Ni(IN) 2(H 2O) 4] (IN=isonicotinate)

Abstract

A three-dimensional supramolecular compound [Ni(IN) 2(H 2O) 4] 1 has been rationally designed and synthesized by hydrothermal method, and the structure was characterized with elemental analysis, FT–IR spectrum and X-ray diffractometer. In the packing structure, the stronger intermolecular O–H⋯O hydrogen-bonded and π–π stacking interactions are the most significant factors of controlling the novel supramolecular sheet fashion for the title compound. The third-order non-linear optical property of compound 1 was also investigated, and it exhibits nicer reverse saturable absorption and self-focusing performance.
