Materials Data on SrCu2(BO3)2 by Materials Project

SrCu2(BO3)2 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.65 Å) and four longer (2.69 Å) Sr–O bond lengths. Cu2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There is two shorter (1.94 Å) and two longer (1.97 Å) Cu–O bond length. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.39 Å) B–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sr2+, one Cu2+, and one B3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one B3+ atom.
