(K2As2F7)2(AsF3)4F2 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two hydrofluoric acid atoms, two AsF3 clusters, and one K2As2F7 cluster. In each AsF3 cluster, there are two inequivalent As sites. In the first As site, As(2) is bonded in a distorted single-bond geometry to one F(1), one F(12), and one F(4) atom. The As(2)-F(1) bond length is 1.79 Å. The As(2)-F(12) bond length is 1.06 Å. The As(2)-F(4) bond length is 2.25 Å. In the second As site, As(4) is bonded in a single-bond geometry to one F(12) atom. The As(4)-F(12) bond length is 1.10 Å. There are six inequivalent F sites. In the first F site, F(12) is bonded in an L-shaped geometry to one As(2) and one As(4) atom. In the second F site, F(1) is bonded in a distorted water-like geometry to one As(2) and one F(7) atom. The F(1)-F(7) bond length is 0.45 Å. In the third F site, F(4) is bonded in a single-bond geometry to one As(2) atom. In the fourth F site, F(6) is bonded in a single-bond geometry to one F(9) atom. The F(6)-F(9) bond length is 1.84 Å. In the fifth F site, F(7) is bonded in a distorted bent 150 degrees geometry to one F(1) and one F(9) atom. The F(7)-F(9) bond length is 0.92 Å. In the sixth F site, F(9) is bonded in a single-bond geometry to one F(6) and one F(7) atom. In the K2As2F7 cluster, there are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one F(11) and one F(2) atom. The K(1)-F(11) bond length is 0.96 Å. The K(1)-F(2) bond length is 2.88 Å. In the second K site, K(2) is bonded in a 1-coordinate geometry to one F(13) and one F(5) atom. The K(2)-F(13) bond length is 3.03 Å. The K(2)-F(5) bond length is 2.28 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted bent 120 degrees geometry to one F(13), one F(3), and one F(8) atom. The As(1)-F(13) bond length is 2.09 Å. The As(1)-F(3) bond length is 1.46 Å. The As(1)-F(8) bond length is 1.57 Å. In the second As site, As(3) is bonded in a single-bond geometry to one F(11) atom. The As(3)-F(11) bond length is 1.54 Å. There are seven inequivalent F sites. In the first F site, F(11) is bonded in a distorted bent 150 degrees geometry to one K(1) and one As(3) atom. In the second F site, F(13) is bonded in a 2-coordinate geometry to one K(2) and one As(1) atom. In the third F site, F(2) is bonded in a 5-coordinate geometry to one K(1), one F(2), one F(3), and two equivalent F(10) atoms. The F(2)-F(2) bond length is 1.13 Å. The F(2)-F(3) bond length is 1.29 Å. There is one shorter (1.31 Å) and one longer (1.58 Å) F(2)-F(10) bond length. In the fourth F site, F(3) is bonded in a distorted single-bond geometry to one As(1) and one F(2) atom. In the fifth F site, F(5) is bonded in a single-bond geometry to one K(2) atom. In the sixth F site, F(8) is bonded in a distorted single-bond geometry to one As(1) atom. In the seventh F site, F(10) is bonded in a distorted single-bond geometry to two equivalent F(2) atoms.
