K Na Hg Ru
KNaRuHg crystallizes in the trigonal R3m space group. K(1) is bonded to one Na(1), three equivalent Ru(1), and one Hg(1) atom to form distorted KNaHgRu3 trigonal bipyramids that share corners with six equivalent K(1)NaHgRu3 trigonal bipyramids and edges with three equivalent Hg(1)KNa3Ru trigonal bipyramids. The K(1)-Na(1) bond length is 2.22 Å. All K(1)-Ru(1) bond lengths are 2.99 Å. The K(1)-Hg(1) bond length is 2.22 Å. Na(1) is bonded in a 7-coordinate geometry to one K(1), three equivalent Ru(1), and three equivalent Hg(1) atoms. All Na(1)-Ru(1) bond lengths are 3.46 Å. All Na(1)-Hg(1) bond lengths are 2.99 Å. Ru(1) is bonded in a 7-coordinate geometry to three equivalent K(1), three equivalent Na(1), and one Hg(1) atom. The Ru(1)-Hg(1) bond length is 2.22 Å. Hg(1) is bonded to one K(1), three equivalent Na(1), and one Ru(1) atom to form distorted HgKNa3Ru trigonal bipyramids that share corners with six equivalent Hg(1)KNa3Ru trigonal bipyramids and edges with three equivalent K(1)NaHgRu3 trigonal bipyramids.
