Neodymium(II) chloride or neodymium dichloride is a chemical compound of neodymium and chlorine with the formula NdCl<sub>2</sub>.
Neodymium(II) chloride can be prepared by reducing neodymium(III) chloride with lithium metal/naphthalene or lithium chloride in THF.
Reduction of neodymium(III) chloride with neodymium metal at temperatures above 650 ðC also yields neodymium(II) chloride:
Neodymium(II) chloride adopts the PbCl<sub>2</sub> (cotunnite) structure. Each Nd<sup>2+</sup> ion is coordinated by nine Cl<sup>−</sup> ions in a tricapped trigonal prismatic arrangement. Seven of the Nd-Cl distances are in the range 2.95-3.14 ÃÂ while two are longer at 3.45ÃÂ ÃÂ .
