Materials Data on Pr2Br2O by Materials Project
Pr2OBr2 is Cyanogen Chloride-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Pr2OBr2 cluster. Pr is bonded in a linear geometry to one O and one Br atom. The Pr–O bond length is 2.17 Å. The Pr–Br bond length is 2.74 Å. O is bonded in a linear geometry to two equivalent Pr atoms. Br is bonded in a single-bond geometry to one Pr atom.
