The crystal structure described by Pr3B2N4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 6-coordinate geometry to six equivalent N(1) atoms. In the second Pr site, Pr(2) is bonded in a distorted body-centered cubic geometry to eight equivalent N(1) atoms. B(1) is bonded in a bent 120 degrees geometry to two equivalent N(1) atoms. N(1) is bonded in a distorted single-bond geometry to two equivalent Pr(2), three equivalent Pr(1), and one B(1) atom. is represented by the CIF file [CIF]
