A new non-centrosymmetric iodate crystal Sm3(IO3)9(HIO3)4 has been successfully synthesized by a hydrothermal method. The crystal structure is a three-dimensional network with samarium polyhedra linked by iodate groups. It shows a moderate second harmonic generation response of 1.1 × KH2PO4 (KDP). The strongest emission in its luminescence spectrum is located at 600 nm under 403 nm excitation. Hence, Sm3(IO3)9(HIO3)4 is a potential orange laser material.
