The compound described by GeNCr3 crystallizes in the tetragonal P-42_1m space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted bent 150 degrees geometry to three equivalent Ge(1) and two equivalent N(1) atoms. In the second Cr site, Cr(2) is bonded in a linear geometry to four equivalent Ge(1) and two equivalent N(1) atoms. Ge(1) is bonded in a distorted q6 geometry to four equivalent Cr(2) and six equivalent Cr(1) atoms. N(1) is bonded to two equivalent Cr(2) and four equivalent Cr(1) atoms to form corner-sharing NCr6 octahedra. The corner-sharing octahedral tilt angles range from 0-26°. is represented by the CIF card [CIF]
