Si2N2Se crystallizes in the orthorhombic Cmc2_1 space group. Si(1) is bonded to three equivalent N(1) and one Se(1) atom to form distorted corner-sharing SiSeN3 tetrahedra. N(1) is bonded in a trigonal planar geometry to three equivalent Si(1) atoms. Se(1) is bonded in a bent 120 degrees geometry to two equivalent Si(1) atoms.
