In the twenty-sixth Pr3+ site, Pr3+ is bonded to four N3-, two O2-, and one Cl1- atom to form distorted PrN4ClO2 pentagonal bipyramids that share a cornercorner with one PrN3ClO3 hexagonal pyramid, a cornercorner with one PrN4ClO2 pentagonal bipyramid, corners with three SiN3O tetrahedra, edges with two PrN3ClO3 hexagonal pyramids, and edges with three SiN3O tetrahedra. There are a spread of Pr–N bond distances ranging from 2.51–2.77 Å. There are one shorter (2.34 Å) and one longer (2.56 Å) Pr–O bond lengths. The Pr–Cl bond length is 2.93 Å. In the twenty-seventh Pr3+ site, Pr3+ is bonded to five N3-, one O2-, and one Cl1- atom to form distorted PrN5ClO hexagonal pyramids that share a cornercorner with one PrN3ClO3 hexagonal pyramid, corners with three PrN2O5 pentagonal bipyramids, corners with three SiN3O tetrahedra, an edgeedge with one PrN5ClO hexa},
