Neodymium(II) chloride


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

Preparation

Neodymium chloride can be prepared by reducing neodymium chloride with lithium metal/naphthalene or lithium chloride in THF.
Reduction of neodymium chloride with neodymium metal at temperatures above 650 °C also yields neodymium chloride:

Structure

Neodymium chloride adopts the PbCl2 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.
