The crystal structure described by Sr3NbN3 crystallizes in the hexagonal P6_3/m space group. Sr(1) is bonded in a see-saw-like geometry to four equivalent N(1) atoms. Nb(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. N(1) is bonded to four equivalent Sr(1) and one Nb(1) atom to form a mixture of distorted corner and edge-sharing NSr4Nb trigonal bipyramids. is represented by the CIF card [CIF]
