Two
polar molybdenum(VI) iodates(V), NH4[MoO3(IO3)] (1) and KRb[(MoO3)2(IO3)2] (2), have been
prepared by a hydrothermal method. They crystallize in noncentrosymmetric
(NCS) space groups Pna21 and Cc, respectively. Structurally, it is interesting that compound 2 has an exclusive one-dimensional [IO3]− chain based on corner-sharing [IO4]3– units in all iodates(V). As for the properties, both compounds exhibit
large second-harmonic generation responses of 4.7 × KH2PO4 (KDP) for compound 1 and 8.5 × KDP
for compound 2 with phase-matching behavior. These results
are in good agreement with the results of the theoretical calculations.
In addition, both compounds also possess large birefringences (Δn) of 0.083 at 1064 nm and 0.146 at 1064 nm, respectively.
These results indicate that the title compounds will have potential
applications as nonlinear optical materials.
