Sr V V V V Ag
SrV4Ag crystallizes in the trigonal R3m space group. Sr(1) is bonded to one V(2) and three equivalent Ag(1) atoms to form distorted corner-sharing SrVAg3 trigonal pyramids. The Sr(1)-V(2) bond length is 2.87 Å. All Sr(1)-Ag(1) bond lengths are 3.09 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 2-coordinate geometry to one V(2), two equivalent V(1), and one Ag(1) atom. The V(1)-V(2) bond length is 0.30 Å. Both V(1)-V(1) bond lengths are 0.17 Å. The V(1)-Ag(1) bond length is 1.47 Å. In the second V site, V(2) is bonded in a distorted rectangular see-saw-like geometry to one Sr(1) and three equivalent V(1) atoms. Ag(1) is bonded to three equivalent Sr(1) and three equivalent V(1) atoms to form distorted corner-sharing AgSr3V3 pentagonal pyramids.
