Abstract

A novel noncentrosymmetric selenide Ag₇TaSe₆ has been successfully synthesized and fully characterized. It features fascinating “three in one” coordination modes which provide valuable insights for designing novel nonlinear optical crystals. Furthermore, detailed theoretical and experimental investigations illustrate the origin of Ag₇TaSe₆'s strong nonlinear optical response.
