Abstract
- A novel antimony fluoride nitrate, Rb3SbF3(NO3)3, fabricated by a rational multi-component design, has been successfully synthesized by a rapid evaporation concentration method. This title compound crystallizes in a polar noncentrosymmetric (NCS) space group (P21) and presents a complicated three-dimensional (3D) network composed of SbO3F3, Rb-centered distorted polyhedra and π-conjugated planar triangular NO3 groups. Rb3SbF3(NO3)3 is a potential UV nonlinear optical material due to its large phase-matchable second harmonic generation (SHG) response of approximately 2.2 times that of KH2PO4 (KDP) and a wide band gap of 3.75 eV. Theoretical calculation analysis was used to rationalize the large SHG effect, which originates from the multi-component synergistic effect including moderately polarizable Rb+ cations, a stereochemically active lone pair effect of Sb3+ and NO3 groups with a π-conjugated planar triangular structure.
