BiN crystallizes in the triclinic P1 space group. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to one N(1) and three equivalent N(2) atoms to form distorted corner-sharing BiN4 trigonal pyramids. In the second Bi site, Bi(2) is bonded to one N(2) and three equivalent N(1) atoms to form distorted corner-sharing BiN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Bi(1) and three equivalent Bi(2) atoms to form distorted corner-sharing NBi4 tetrahedra. In the second N site, N(2) is bonded to one Bi(2) and three equivalent Bi(1) atoms to form distorted corner-sharing NBi4 tetrahedra.
BiN crystallizes in the triclinic P1 space group. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to one N(1) and three equivalent N(2) atoms to form distorted corner-sharing BiN4 trigonal pyramids. The Bi(1)-N(1) bond length is 2.27 Å. There are a spread of Bi(1)-N(2) bond distances ranging from 2.28-2.66 Å. In the second Bi site, Bi(2) is bonded to one N(2) and three equivalent N(1) atoms to form distorted corner-sharing BiN4 trigonal pyramids. The Bi(2)-N(2) bond length is 2.27 Å.
