The compound described by NaPr2Cl6 crystallizes in the trigonal P-3 space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent Cl(1) atoms. Pr(1) is bonded in a 9-coordinate geometry to nine equivalent Cl(1) atoms. Cl(1) is bonded to one Na(1) and three equivalent Pr(1) atoms to form a mixture of edge and corner-sharing ClNaPr3 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
