The compound described by Li2Ba(MgSi)2 crystallizes in the trigonal R-3m space group. Li(1) is bonded in a 6-coordinate geometry to three equivalent Ba(1), three equivalent Mg(1), and three equivalent Si(1) atoms. Ba(1) is bonded in a 14-coordinate geometry to six equivalent Li(1), two equivalent Mg(1), and six equivalent Si(1) atoms. Mg(1) is bonded in a 7-coordinate geometry to three equivalent Li(1), one Ba(1), and four equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to three equivalent Li(1), three equivalent Ba(1), and four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
