The first alkali‐metal vanadium iodate fluoride, CsVO 2 F(IO 3 ), with a novel 3D anionic framework, has been rationally designed and hydrothermally synthesized. The 3D [VO 2 F(IO 3 )] − framework in CsVO 2 F(IO 3 ) is built from 0D Λ‐shaped cis ‐[VO 3 F(IO 3 ) 2 ] 4− polyanions via corner‐sharing of oxo anions and bridging of the iodate groups. CsVO 2 F(IO 3 ) displays both a strong second‐harmonic generation (SHG) 1.1 times as strong as KTiOPO 4 (KTP) under 2.05 μm laser radiation and high laser‐induced damage threshold (LIDT) of 107.9 MW cm −2 . This work provides a new route to design SHG crystals with stable 3D anionic structures from low‐dimensional structural building units.
