Sr Re Re Si
SrRe2Si crystallizes in the triclinic P1 space group. Sr(1) is bonded in a distorted single-bond geometry to four equivalent Re(2) and one Si(1) atom. There are a spread of Sr(1)-Re(2) bond distances ranging from 2.85-3.32 Å. The Sr(1)-Si(1) bond length is 1.91 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 1-coordinate geometry to one Re(2) and one Si(1) atom. The Re(1)-Re(2) bond length is 2.32 Å. The Re(1)-Si(1) bond length is 1.15 Å. In the second Re site, Re(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1), one Re(1), two equivalent Re(2), and one Si(1) atom. Both Re(2)-Re(2) bond lengths are 2.93 Å. The Re(2)-Si(1) bond length is 2.93 Å. Si(1) is bonded in a 2-coordinate geometry to one Sr(1), one Re(1), and one Re(2) atom.
