PFNBr is Indium-like structured and crystallizes in the orthorhombic Cmc2_1 space group. The structure is zero-dimensional and consists of four PFNBr clusters. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent N(1), one Br(1), and one F(2) atom to form distorted corner-sharing PBrN2F tetrahedra. In the second P site, P(2) is bonded to one N(1), one N(2), one Br(2), and one F(1) atom to form distorted corner-sharing PBrN2F tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to two equivalent P(2) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a single-bond geometry to one P(1) atom. In the second Br site, Br(2) is bonded in a single-bond geometry to one P(2) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one P(2) atom. In the second F site, F(2) is bonded in a single-bond geometry to one P(1) atom.

In the first P site, P(1) is bonded to two equivalent N(1), one Br(1), and one F(2) atom to form distorted corner-sharing PBrN2F tetrahedra. Both P(1)-N(1) bond lengths are 1.59 Å. The P(1)-Br(1) bond length is 2.18 Å. The P(1)-F(2) bond length is 1.57 Å. In the second P site, P(2) is bonded to one N(1), one N(2), one Br(2), and one F(1) atom to form distorted corner-sharing PBrN2F tetrahedra. The P(2)-N(1) bond length is 1.59 Å.
