Ba2CrN2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded to five equivalent N(1) atoms to form a mixture of edge and corner-sharing BaN5 square pyramids. Cr(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to five equivalent Ba(1) and one Cr(1) atom to form a mixture of distorted edge and corner-sharing NBa5Cr octahedra. The corner-sharing octahedral tilt angles range from 0-7°.
Ba2CrN2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded to five equivalent N(1) atoms to form a mixture of edge and corner-sharing BaN5 square pyramids. All Ba(1)-N(1) bond lengths are 2.95 Å. Cr(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Cr(1)-N(1) bond lengths are 1.78 Å. N(1) is bonded to five equivalent Ba(1) and one Cr(1) atom to form a mixture of distorted edge and corner-sharing NBa5Cr octahedra. The corner-sharing octahedral tilt angles range from 0-7°.
