Sr Y Mn Ag
SrYMnAg crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 5-coordinate geometry to one Y(1), three equivalent Mn(1), and one Ag(1) atom. The Sr(1)-Y(1) bond length is 2.05 Å. All Sr(1)-Mn(1) bond lengths are 3.01 Å. The Sr(1)-Ag(1) bond length is 2.05 Å. Y(1) is bonded to one Sr(1) and three equivalent Ag(1) atoms to form distorted YSrAg3 trigonal pyramids that share  a cornercorner with one Ag(1)SrY3Mn trigonal bipyramid and corners with six equivalent Y(1)SrAg3 trigonal pyramids. All Y(1)-Ag(1) bond lengths are 3.01 Å. Mn(1) is bonded in a 4-coordinate geometry to three equivalent Sr(1) and one Ag(1) atom. The Mn(1)-Ag(1) bond length is 2.05 Å. Ag(1) is bonded to one Sr(1), three equivalent Y(1), and one Mn(1) atom to form distorted AgSrY3Mn trigonal bipyramids that share corners with six equivalent Ag(1)SrY3Mn trigonal bipyramids and  a cornercorner with one Y(1)SrAg3 trigonal pyramid.
