CaRe2Si is Heusler structured and crystallizes in the cubic Fm-3m space group. Ca(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Re(1) and six equivalent Si(1) atoms. Re(1) is bonded to four equivalent Ca(1) and four equivalent Si(1) atoms to form a mixture of distorted face, corner, and edge-sharing ReCa4Si4 tetrahedra. Si(1) is bonded in a 14-coordinate geometry to six equivalent Ca(1) and eight equivalent Re(1) atoms.
