V Si Ag Ag
VAg2Si crystallizes in the monoclinic Cm space group. V(1) is bonded in a 5-coordinate geometry to four equivalent Ag(1) and one Si(1) atom. There are two shorter (1.03 Å) and two longer (3.20 Å) V(1)-Ag(1) bond lengths. The V(1)-Si(1) bond length is 2.52 Å. Ag(1) is bonded in a 2-coordinate geometry to two equivalent V(1), one Ag(1), and one Si(1) atom. The Ag(1)-Ag(1) bond length is 0.55 Å. The Ag(1)-Si(1) bond length is 1.80 Å. Si(1) is bonded in a 3-coordinate geometry to one V(1) and two equivalent Ag(1) atoms.
