Infobox references

Neodymium(II) chloride or neodymium dichloride is a chemical compound of neodymium and chlorine with the formula NdCl2.

## Preparation

Neodymium(II) chloride can be prepared by reducing neodymium(III) chloride with lithium metal/naphthalene or lithium chloride in THF.[2]

Reduction of neodymium(III) chloride with neodymium metal at temperatures above 650 °C also yields neodymium(II) chloride:[3]

2 NdCl3 \+ Nd → 3 NdCl2

## Structure

Neodymium(II) chloride adopts the PbCl2 (cotunnite) structure. Each Nd2+ ion is coordinated by nine Cl− ions in a tricapped trigonal prismatic arrangement. Seven of the Nd-Cl distances are in the range 2.95-3.14 Å while two are longer at 3.45 Å.[4][5]
