K Sn Ru Ru
KRu2Sn crystallizes in the monoclinic Cm space group. K(1) is bonded in a 4-coordinate geometry to four equivalent Ru(1), four equivalent Ru(2), and one Sn(1) atom. There are a spread of K(1)-Ru(1) bond distances ranging from 3.44-3.99 Å. There are a spread of K(1)-Ru(2) bond distances ranging from 1.84-2.74 Å. The K(1)-Sn(1) bond length is 3.34 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 10-coordinate geometry to four equivalent K(1), one Ru(2), four equivalent Ru(1), and one Sn(1) atom. The Ru(1)-Ru(2) bond length is 3.25 Å. All Ru(1)-Ru(1) bond lengths are 3.20 Å. The Ru(1)-Sn(1) bond length is 3.51 Å. In the second Ru site, Ru(2) is bonded in a 4-coordinate geometry to four equivalent K(1), one Ru(1), and one Sn(1) atom. The Ru(2)-Sn(1) bond length is 3.51 Å. Sn(1) is bonded in a 7-coordinate geometry to one K(1), one Ru(1), one Ru(2), and four equivalent Sn(1) atoms. All Sn(1)-Sn(1) bond lengths are 3.20 Å.
