Herein, we reported two alkali metal molybdenum(VI) iodates, namely, NaMoO3(IO3) and gamma-KMoO3(IO3) with 1D and 3D [MoO3(IO3)]- anionic architectures, respectively. The novel 1D chain in NaMoO3(IO3) and the 3D network in gamma-KMoO3(IO3) are constructed by the 0D A-shaped cis-[MoO4(IO3)2]4- building units interconnected by bridging IO3- anions as well as the corner-sharing of oxo anions. Importantly, the polar gamma-KMoO3(IO3) exhibits a very large second-harmonic generation (SHG) effect of 12 x KH2PO4 (KDP) under 1064 nm laser radiation, a high laser-Induced damage threshold value (52 x AgGaS2), and a moderate birefringence of 0.087@1064 nm, whereas the centrosymmetric NaMoO3(IO3) has a large birefringence of 0.208@1064 nm. This study further proves the useful route of exploring promising optical materials via assembling the 0D basic building units into higher dimensional anionic architectures. (c) 2021 Elsevier B.V.
