Two mixed‐metal gallium iodate fluorides, namely, α‐ and β‐Ba2[GaF4(IO3)2](IO3) (1 and 2), have been designed by the aliovalent substitutions of α‐ and β‐Ba2[VO2F2(IO3)2](IO3) (3 and 4) involving one cationic and two anionic sites. Both 1 and 2 display large second‐harmonic generation responses (≈6×...
