A new nonlinear compound, TiO(IO 3 ) 2 , was synthesized by the hydrothermal method and characterized by single‐crystal X‐ray diffraction. It crystallizes in the acentric Cmc 2 1 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) Å 3 . 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 KTiOPO 4 (KTP) material. IR spectroscopy and NLO efficiency studies on a powder sample suggest that TiO(IO 3 ) 2 is a good potential NLO material.
