The material described by Ba(CrN)2 crystallizes in the trigonal P-3m1 space group. Ba(1) is bonded in a 6-coordinate geometry to six equivalent N(1) atoms. Cr(1) is bonded to four equivalent N(1) atoms to form a mixture of corner and edge-sharing CrN4 tetrahedra. N(1) is bonded in a 7-coordinate geometry to three equivalent Ba(1) and four equivalent Cr(1) atoms. is represented by the CIF card [CIF]
