The material described by Pr3Nb(O2Cl)3 crystallizes in the hexagonal P6_3/m space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent O(1) and four equivalent Cl(1) atoms. Nb(1) is bonded in a distorted pentagonal pyramidal geometry to six equivalent O(1) atoms. O(1) is bonded to three equivalent Pr(1) and one Nb(1) atom to form a mixture of edge and corner-sharing OPr3Nb tetrahedra. Cl(1) is bonded in a see-saw-like geometry to four equivalent Pr(1) atoms. is represented by the CIF file [CIF]
