Abstract

Sr3Cr is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded to eight Sr and four equivalent Cr atoms to form distorted SrSr8Cr4 cuboctahedra that share corners with twelve equivalent SrSr8Cr4 cuboctahedra, edges with eight equivalent CrSr12 cuboctahedra, edges with sixteen SrSr8Cr4 cuboctahedra, faces with four equivalent CrSr12 cuboctahedra, and faces with fourteen SrSr8Cr4 cuboctahedra. There are four shorter (3.90 Å) and four longer (3.93 Å) Sr–Sr bond lengths. All Sr–Cr bond lengths are 3.90 Å. In the second Sr site, Sr is bonded to eight equivalent Sr and four equivalent Cr atoms to form distorted SrSr8Cr4 cuboctahedra that share corners with four equivalent SrSr8Cr4 cuboctahedra, corners with eight equivalent CrSr12 cuboctahedra, edges with twenty-four SrSr8Cr4 cuboctahedra, faces with six equivalent CrSr12 cuboctahedra, and faces with twelve SrSr8Cr4 cuboctahedra. All Sr–Cr bond lengths are 3.93 Å. Cr is bonded to twelve Sr atoms to form CrSr12 cuboctahedra that share corners with four equivalent CrSr12 cuboctahedra, corners with eight equivalent SrSr8Cr4 cuboctahedra, edges with eight equivalent CrSr12 cuboctahedra, edges with sixteen equivalent SrSr8Cr4 cuboctahedra, faces with four equivalent CrSr12 cuboctahedra, andmore »« less
