The material described by RbLaSi(CN2)4 crystallizes in the tetragonal I-4 space group. Rb(1) is bonded in a 12-coordinate geometry to four equivalent C(1), four equivalent N(1), and four equivalent N(2) atoms. La(1) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent N(2) atoms. Si(1) is bonded in a tetrahedral geometry to four equivalent N(2) atoms. C(1) is bonded in a linear geometry to one Rb(1), one N(1), and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one La(1), and one C(1) atom. In the second N site, N(2) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one La(1), one Si(1), and one C(1) atom. is represented by the CIF file [CIF]
