The crystal structure described by RbSi2N3 crystallizes in the orthorhombic Cmc2_1 space group. Rb(1) is bonded in a 10-coordinate geometry to four equivalent N(2) and six equivalent N(1) atoms. Si(1) is bonded to one N(2) and three equivalent N(1) atoms to form corner-sharing SiN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded in a distorted linear geometry to four equivalent Rb(1) and two equivalent Si(1) atoms. In the second N site, N(1) is bonded in a distorted trigonal planar geometry to three equivalent Rb(1) and three equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
