Abstract
- A novel antimony fluoride nitrate, Rb<subscript>3</subscript>SbF<subscript>3</subscript>(NO<subscript>3</subscript>)<subscript>3</subscript>, 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 (P2<subscript>1</subscript>) and presents a complicated three-dimensional (3D) network composed of SbO<subscript>3</subscript>F<subscript>3</subscript>, Rb-centered distorted polyhedra and π-conjugated planar triangular NO<subscript>3</subscript> groups. Rb<subscript>3</subscript>SbF<subscript>3</subscript>(NO<subscript>3</subscript>)<subscript>3</subscript> 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 KH<subscript>2</subscript>PO<subscript>4</subscript> (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<superscript>+</superscript> cations, a stereochemically active lone pair effect of Sb<superscript>3+</superscript> and NO<subscript>3</subscript> groups with a π-conjugated planar triangular structure.
