The structure described by TaNSe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ta(1) is bonded in a 4-coordinate geometry to four equivalent N(1) and five equivalent Se(1) atoms. N(1) is bonded to four equivalent Ta(1) atoms to form a mixture of corner and edge-sharing NTa4 tetrahedra. Se(1) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms. is represented by the CIF card [CIF]
