Cr Si Si Ag
CrAgSi2 crystallizes in the triclinic P1 space group. Cr(1) is bonded in a single-bond geometry to one Ag(1), two equivalent Si(1), and two equivalent Si(2) atoms. The Cr(1)-Ag(1) bond length is 0.31 Å. There is one shorter (2.73 Å) and one longer (3.10 Å) Cr(1)-Si(1) bond length. There is one shorter (2.40 Å) and one longer (2.82 Å) Cr(1)-Si(2) bond length. Ag(1) is bonded in a single-bond geometry to one Cr(1), two equivalent Si(1), and two equivalent Si(2) atoms. There is one shorter (2.40 Å) and one longer (2.82 Å) Ag(1)-Si(1) bond length. There is one shorter (2.73 Å) and one longer (3.10 Å) Ag(1)-Si(2) bond length. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 8-coordinate geometry to two equivalent Cr(1), two equivalent Ag(1), two equivalent Si(1), and two equivalent Si(2) atoms. Both Si(1)-Si(1) bond lengths are 2.70 Å. There is one shorter (2.09 Å) and one longer (2.51 Å) Si(1)-Si(2) bond length. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to two equivalent Cr(1), two equivalent Ag(1), two equivalent Si(1), and two equivalent Si(2) atoms. Both Si(2)-Si(2) bond lengths are 2.70 Å.
