(K)4K4Al3(SiO8)3(AlSi)3 is Indium-derived structured and crystallizes in the trigonal R3 space group. The structure is zero-dimensional and consists of nine 11145-27-0 molecules, three K clusters, and three K4Al3(SiO8)3 clusters. In each K cluster, K(3,4) is bonded in a 3-coordinate geometry to three equivalent K(3,4) atoms. All K(3,4)-K(3,4) bond lengths are 0.84 Å. In each K4Al3(SiO8)3 cluster, there are two inequivalent K sites. In the first K site, K(1) is bonded in a trigonal non-coplanar geometry to one O(2), one O(3), one O(4), one O(5), one O(6), and one O(7) atom. The K(1)-O(2) bond length is 2.83 Å. The K(1)-O(3) bond length is 2.83 Å. The K(1)-O(4) bond length is 2.83 Å. The K(1)-O(5) bond length is 0.81 Å. The K(1)-O(6) bond length is 0.81 Å. The K(1)-O(7) bond length is 0.81 Å. In the second K site, K(2) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) and three equivalent O(8) atoms. All K(2)-O(1) bond lengths are 2.83 Å. All K(2)-O(8) bond lengths are 0.81 Å. Al(1) is bonded in a distorted single-bond geometry to one O(6) atom. The Al(1)-O(6) bond length is 2.24 Å. Si(1) is bonded in a 2-coordinate geometry to one O(6) and one O(7) atom. The Si(1)-O(6) bond length is 2.46 Å. The Si(1)-O(7) bond length is 2.30 Å. There are nine inequivalent O sites. In the first O site, O(5) is bonded in a single-bond geometry to one K(1) atom. The O(5)-K(1) bond length is 0.81 Å. In the second O site, O(4) is bonded in a 4-coordinate geometry to one K(1), one O(2), and two equivalent O(4) atoms. The O(4)-O(2) bond length is 1.52 Å. Both O(4)-O(4) bond lengths are 1.29 Å. In the third O site, O(5) is bonded in a single-bond geometry to one K(1) atom. In the fourth O site, O(6) is bonded in a single-bond geometry to one K(1), one Al(1), and one Si(1) atom. In the fifth O site, O(7) is bonded in a single-bond geometry to one K(1) and one Si(1) atom. In the sixth O site, O(8) is bonded in a single-bond geometry to one K(2) atom. In the seventh O site, O(1) is bonded in a 4-coordinate geometry to one K(2), one O(2), and two equivalent O(3) atoms. The O(1)-O(2) bond length is 1.29 Å. There is one shorter (1.29 Å) and one longer (1.52 Å) O(1)-O(3) bond length. In the eighth O site, O(2) is bonded in a 4-coordinate geometry to one K(1), one O(1), one O(3), and one O(4) atom. The O(2)-O(3) bond length is 1.29 Å. In the ninth O site, O(3) is bonded in a 4-coordinate geometry to one K(1), one O(2), and two equivalent O(1) atoms.
