KEuSiS4 crystallizes in the triclinic P-1 space group. K(1) is bonded in a distorted L-shaped geometry to one K(1), one Si(1), one S(1), one S(2), and one S(3) atom. The K(1)-K(1) bond length is 0.87 Å. The K(1)-Si(1) bond length is 3.20 Å. The K(1)-S(1) bond length is 2.25 Å. The K(1)-S(2) bond length is 3.61 Å. The K(1)-S(3) bond length is 3.25 Å. Eu(1) is bonded in a distorted L-shaped geometry to one Si(1), one S(3), and two equivalent S(4) atoms. The Eu(1)-Si(1) bond length is 2.51 Å. The Eu(1)-S(3) bond length is 3.71 Å. There is one shorter (0.83 Å) and one longer (1.00 Å) Eu(1)-S(4) bond length. Si(1) is bonded in a 3-coordinate geometry to one K(1), one Eu(1), and one S(4) atom. The Si(1)-S(4) bond length is 2.65 Å. There are four inequivalent S sites. In the first S site, S(1) is bonded in a distorted single-bond geometry to one K(1) and one S(3) atom. The S(1)-S(3) bond length is 2.32 Å. In the second S site, S(2) is bonded in a 4-coordinate geometry to one K(1), one S(2), and two equivalent S(3) atoms. The S(2)-S(2) bond length is 1.96 Å. There is one shorter (1.33 Å) and one longer (1.99 Å) S(2)-S(3) bond length. In the third S site, S(3) is bonded in a 5-coordinate geometry to one K(1), one Eu(1), one S(1), and two equivalent S(2) atoms. In the fourth S site, S(4) is bonded in a water-like geometry to two equivalent Eu(1) and one Si(1) atom.
