Preparation

It can be prepared by reacting neodymium oxide and molybdenum trioxide at a high temperature:^[2]

Nd₂O₃ + 3MoO₃ → Nd₂(MoO₄)₃

It can also be prepared by reacting neodymium nitrate and (NH₄)₆Mo₇O₂₄, treating the obtained precipitate at a high temperature.^[1]

Properties

It reacts with sodium molybdate at a high temperature to obtain NaNd(MoO₄)₂.^[3] It reacts at roughly 350°C to 700°C with hydrogen sulfide to obtain neodymium sulfide and molybdenum disulfide.^[4] At roughly 780K to 870K, it can be reduced by hydrogen to obtain Nd₂Mo₃O₉.^[5]
