Li Mg Zn Ag
LiMgAgZn crystallizes in the trigonal R3m space group. Li(1) is bonded in a single-bond geometry to four equivalent Mg(1), three equivalent Ag(1), and one Zn(1) atom. There is one shorter (2.74 Å) and three longer (2.83 Å) Li(1)-Mg(1) bond lengths. All Li(1)-Ag(1) bond lengths are 2.70 Å. The Li(1)-Zn(1) bond length is 1.51 Å. Mg(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), three equivalent Ag(1), and three equivalent Zn(1) atoms. All Mg(1)-Ag(1) bond lengths are 2.70 Å. All Mg(1)-Zn(1) bond lengths are 2.70 Å. Ag(1) is bonded in a 10-coordinate geometry to three equivalent Li(1), three equivalent Mg(1), and four equivalent Zn(1) atoms. There is one shorter (2.74 Å) and three longer (2.83 Å) Ag(1)-Zn(1) bond lengths. Zn(1) is bonded in a single-bond geometry to one Li(1), three equivalent Mg(1), and four equivalent Ag(1) atoms.
