A new nonlinear compound, TiO(IO3)2, was synthesized by the hydrothermal method and characterized by single-crystal X-ray diffraction. It crystallizes in the acentric Cmc21 space group with the following lattice parameters: a = 10.222(1) Å, b = 8.254(1) Å, c = 7.277(1) Å, and V = 613.98(13) Å3. The structure has alternating Ti-O bond lengths, short [Ti-O 1.733(12) Å, titanyl bond] and long [Ti-O 2.113(12) Å], as observed in the KTiOPO4 (KTP) material. IR spectroscopy and NLO efficiency studies on a powder sample suggest that TiO(IO3)2 is a good potential NLO material.
