The crystal structure described by K3SnHF8 crystallizes in the monoclinic C2/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent H(1), two equivalent F(1), two equivalent F(2), and two equivalent F(5) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to one F(3), one F(4), two equivalent F(1), two equivalent F(2), and two equivalent F(5) atoms. Sn(1) is bonded in an octahedral geometry to one F(3), one F(4), two equivalent F(1), and two equivalent F(5) atoms. H(1) is bonded in a linear geometry to two equivalent K(1) and two equivalent F(2) atoms. There are five inequivalent F sites. In the first F site, F(5) is bonded in a distorted rectangular see-saw-like geometry to one K(1), two equivalent K(2), and one Sn(1) atom. In the second F site, F(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Sn(1) atom. In the third F site, F(2) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one H(1) atom. In the fourth F site, F(3) is bonded in a 3-coordinate geometry to two equivalent K(2) and one Sn(1) atom. In the fifth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent K(2) and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
