Ce2BiN crystallizes in the tetragonal P4/nmm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to four equivalent Bi(1) and four equivalent N(1) atoms to form a mixture of distorted edge and face-sharing CeBi4N4 trigonal pyramids. In the second Ce site, Ce(2) is bonded in a single-bond geometry to five equivalent Bi(1) and one N(1) atom. Bi(1) is bonded to four equivalent Ce(1) and five equivalent Ce(2) atoms to form distorted BiCe9 square pyramids that share corners with four equivalent Bi(1)Ce9 square pyramids, corners with five equivalent N(1)Ce5 trigonal bipyramids, edges with eight equivalent Bi(1)Ce9 square pyramids, faces with four equivalent Bi(1)Ce9 square pyramids, and faces with five equivalent N(1)Ce5 trigonal bipyramids. N(1) is bonded to one Ce(2) and four equivalent Ce(1) atoms to form distorted NCe5 trigonal bipyramids that share corners with five equivalent Bi(1)Ce9 square pyramids, corners with four equivalent N(1)Ce5 trigonal bipyramids, edges with four equivalent N(1)Ce5 trigonal bipyramids, and faces with five equivalent Bi(1)Ce9 square pyramids.

In the first Ce site, Ce(1) is bonded to four equivalent Bi(1) and four equivalent N(1) atoms to form a mixture of distorted edge and face-sharing CeBi4N4 trigonal pyramids. All Ce(1)-Bi(1) bond lengths are 3.68 Å. All Ce(1)-N(1) bond lengths are 2.50 Å. In the second Ce site, Ce(2) is bonded in a single-bond geometry to five equivalent Bi(1) and one N(1) atom. There are four shorter (3.35 Å) and one longer (3.52 Å) Ce(2)-Bi(1) bond length. The Ce(2)-N(1) bond length is 2.25 Å. Bi(1) is bonded to four equivalent Ce(1) and five equivalent Ce(2) atoms to form distorted BiCe9 square pyramids that share corners with four equivalent Bi(1)Ce9 square pyramids, corners with five equivalent N(1)Ce5 trigonal bipyramids, edges with eight equivalent Bi(1)Ce9 square pyramids, faces with four equivalent Bi(1)Ce9 square pyramids, and faces with five equivalent N(1)Ce5 trigonal bipyramids.
