Neodymium(II) iodide or neodymium diiodide is an inorganic salt of iodine and neodymium the formula NdI2. Neodymium uses the +2 oxidation state in the compound.
Formation
Neodymium(II) iodide can be made by heating molten neodymium(III) iodide with neodymium metal at 800 and 580°C for 12 hours.[2]
Properties
Neodymium(II) iodide is not stoichiometric, and has a formula of closer to NdI1.95.[2] Neodymium(II) iodide melts at 562°C.[3] It is a violet compound.
Neodymium(II) iodide is an electrical insulator.[2]
Reactions
Neodymium(II) iodide reacts with organohalides by extracting the halogen, resulting in dimers, oligomers or reactions with the solvent.[4]
Solvates are known with tetrahydrofuran and dimethoxyethane: NdI2(THF)2 and NdI2(DME)2[5]
Neodymium(II) iodide reduces hot nitrogen to form an iodide nitride: (NdI2)3N which with THF also gives (NdI)3N2.[6]
It reacts with cyclopentadiene in THF to give CpNdI2(THF)3.[7]
