BPNBr2Cl3 is Indium-like structured and crystallizes in the orthorhombic Cmce space group. The structure is zero-dimensional and consists of four BPNBr2Cl3 clusters. B(1) is bonded to two equivalent N(1) and two equivalent Br(1) atoms to form BBr2N2 tetrahedra that share corners with two equivalent P(1)NCl3 tetrahedra and  an edgeedge with one B(1)Br2N2 tetrahedra. P(1) is bonded to one N(1), one Cl(2), and two equivalent Cl(1) atoms to form PNCl3 tetrahedra that share corners with two equivalent B(1)Br2N2 tetrahedra. N(1) is bonded in a distorted T-shaped geometry to two equivalent B(1) and one P(1) atom. Br(1) is bonded in a single-bond geometry to one B(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one P(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one P(1) atom.
