The crystal structure described by Ca5(AgN2)2 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a distorted square co-planar geometry to four equivalent N(1) atoms. In the second Ca site, Ca(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. Ag(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to one Ca(1), four equivalent Ca(2), and one Ag(1) atom to form a mixture of edge and corner-sharing NCa5Ag octahedra. The corner-sharing octahedral tilt angles range from 1-19°. is represented by the Crystallographic Information File (CIF) [CIF]
