Materials Data on SrCu2O3 by Materials Project
SrCu2O3 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.63–2.71 Å. Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.91 Å) and two longer (1.99 Å) Cu–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Sr2+ and three equivalent Cu2+ atoms to form distorted OSr2Cu3 trigonal bipyramids that share corners with five equivalent OSr4Cu2 octahedra, corners with six equivalent OSr2Cu3 trigonal bipyramids, edges with three equivalent OSr2Cu3 trigonal bipyramids, and faces with two equivalent OSr4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 0–64°. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Cu2+ atoms to form distorted OSr4Cu2 octahedra that share corners with four equivalent OSr4Cu2 octahedra, corners with ten equivalent OSr2Cu3 trigonal bipyramids, edges with four equivalent OSr4Cu2 octahedra, and faces with four equivalent OSr2Cu3 trigonal bipyramids. The corner-sharing octahedral tilt angles are 2°.
