Sr Be Be Co
SrBe2Co crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 13-coordinate geometry to four equivalent Sr(1), four equivalent Be(1), four equivalent Be(2), and one Co(1) atom. All Sr(1)-Sr(1) bond lengths are 2.94 Å. There are a spread of Sr(1)-Be(1) bond distances ranging from 3.21-3.36 Å. There are a spread of Sr(1)-Be(2) bond distances ranging from 3.21-3.36 Å. The Sr(1)-Co(1) bond length is 2.78 Å. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Be(2), and four equivalent Co(1) atoms. The Be(1)-Be(2) bond length is 1.74 Å. There are a spread of Be(1)-Co(1) bond distances ranging from 2.47-2.66 Å. In the second Be site, Be(2) is bonded to four equivalent Sr(1), one Be(1), and four equivalent Co(1) atoms to form a mixture of distorted face and edge-sharing BeSr4BeCo4 square pyramids. There are a spread of Be(2)-Co(1) bond distances ranging from 1.98-2.21 Å. Co(1) is bonded in a 9-coordinate geometry to one Sr(1), four equivalent Be(1), and four equivalent Be(2) atoms.
