The crystal structure described by SrCa2N2 crystallizes in the orthorhombic Pmmn space group. Sr(1) is bonded in a distorted bent 120 degrees geometry to four equivalent N(1) atoms. Ca(1) is bonded to five equivalent N(1) atoms to form a mixture of distorted edge and corner-sharing CaN5 square pyramids. N(1) is bonded in a 7-coordinate geometry to two equivalent Sr(1) and five equivalent Ca(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
