NaRuAgZn crystallizes in the trigonal R3m space group. Na(1) is bonded in a 11-coordinate geometry to three equivalent Ru(1), four equivalent Ag(1), and four equivalent Zn(1) atoms. All Na(1)-Ru(1) bond lengths are 2.73 Å. There is one shorter (2.44 Å) and three longer (2.88 Å) Na(1)-Ag(1) bond lengths. There is one shorter (2.05 Å) and three longer (3.07 Å) Na(1)-Zn(1) bond lengths. Ru(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), one Ag(1), and three equivalent Zn(1) atoms. The Ru(1)-Ag(1) bond length is 2.05 Å. All Ru(1)-Zn(1) bond lengths are 2.73 Å. Ag(1) is bonded in a distorted linear geometry to four equivalent Na(1) and one Ru(1) atom. Zn(1) is bonded in a distorted single-bond geometry to four equivalent Na(1) and three equivalent Ru(1) atoms.
