The material described by Ge6Bi3N11 crystallizes in the tetragonal P4bm space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form corner-sharing GeN4 tetrahedra. In the second Ge site, Ge(2) is bonded to one N(3), one N(4), and two equivalent N(2) atoms to form corner-sharing GeN4 trigonal pyramids. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to one N(3), one N(4), two equivalent N(1), and two equivalent N(2) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent N(2) atoms. There are four inequivalent N sites. In the first N site, N(3) is bonded to one Ge(2), two equivalent Ge(1), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing NGe3Bi trigonal pyramids. In the second N site, N(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(2) and two equivalent Bi(1) atoms. In the third N site, N(1) is bonded to two equivalent Ge(1), one Bi(1), and one Bi(2) atom to form distorted NGe2Bi2 trigonal pyramids that share  a cornercorner with one N(3)Ge3Bi trigonal pyramid, corners with two equivalent N(1)Ge2Bi2 trigonal pyramids,  an edgeedge with one N(3)Ge3Bi trigonal pyramid, and edges with two equivalent N(1)Ge2Bi2 trigonal pyramids. In the fourth N site, N(2) is bonded in a distorted bent 120 degrees geometry to one Ge(1), one Ge(2), one Bi(1), and one Bi(2) atom. is represented by the CIF file [CIF]
