Abstract

Explorations of new second-order nonlinear optical (NLO) materials in the K^I-M^II -I^V-O systems led to four novel mixed metal iodates, namely, K₂M(IO₃)₄(H ₂O)₂ (M = Mn, Co, Zn, Mg). The four compounds are isostructural and crystallize in space group I2 which is in the chiral and polar crystal class 2. Their structure features zero-dimensional {M(IO ₃)₄(H₂O)₂}^2- anions that are separated by K⁺ cations. The M(II) centers are ligated by two aqua ligands in trans fashion and four monodentate iodate anions. The K ⁺ cation is eight-coordinated by two iodate anions in bidentate chelating fashion and four other iodates in a unidentate fashion. Second harmonic generation (SHG) measurements indicate that K₂Zn(IO ₃)₄(H₂O)₂ and K ₂Mg(IO₃)₄(H₂O)₂ display moderate SHG responses that are approximately 2.3 and 1.4 times of KH ₂PO₄ (KDP), respectively, and they are also phase-matchable. The SHG response of K₂Co(IO₃) ₄(H₂O)₂ is much weaker (about 0.3 - KDP), and no obvious SHG signal was detected for K₂Mn(IO₃) ₄(H₂O)₂. Results of optical property calculations for the Zn and Mg phases revealed SHG responses of approximately 5.3 and 4.7 times of KDP, respectively, the order of Zn > Mg is in good agreement with the experiment data.
