Abstract

A series of neodymium periodate, mixed periodate-iodate and iodate structures have been synthesized via periodic acid flux reactions and characterized through single-crystal x-ray diffraction. Critically, the utilization of a sacrificial oxidant, sodium bismuthate (NaBiO3), helps to stave off the thermal reduction of periodate. Through the precise control of reaction time and amount of NaBiO3, this facile synthetic technique illuminates new pathways to creating mixed valent iodine compounds and a route to new iodate compounds as well. Herein, we explore the in-situ periodic acid flux redox reactions with neodymium nitrate and sodium bismuthate. The resulting products reveal the evolution of compounds formed as these redox reactions proceed forward with time and presence of NaBiO3.
