Sr Sr Ca Co
Sr2CaCo crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 1-coordinate geometry to four equivalent Co(1) atoms. There are a spread of Sr(1)-Co(1) bond distances ranging from 3.07-4.03 Å. Ca(1) is bonded in a 1-coordinate geometry to three equivalent Co(1) atoms. There is one shorter (3.08 Å) and two longer (3.69 Å) Ca(1)-Co(1) bond lengths. Co(1) is bonded in a 11-coordinate geometry to eight equivalent Sr(1) and three equivalent Ca(1) atoms.
