The first rare‐earth‐metal iodate fluoride , Ce(IO 3 ) 2 F 2 ⋅ H 2 O, has been synthesized by a hydrothermal method. The crystal structure can be described as CeO 5 F 4 polyhedra connected with isolated IO 3 groups to form 1D infinite ∞ 1 [Ce(IO 3 ) 2 F 2 ] chains, which interconnect with each other through weak hydrogen bonds to construct the whole structure. The cover design combines the elements of laser frequency doubling using NLO crystals, the structure of Ce(IO 3 ) 2 F 2 ⋅ H 2 O, and geometry to create a “surrealistic world”. The good optical properties with a large second harmonic generation response confirm that the compound has potential application in the field of NLO materials.
