| Description: | In order to eliminate some contradictions found in the literature for the MIn4S4 (M – In', Sn, Ge)
phases, the crystal structures of these phases reported earlier have been analyzed by using the bond
valence model. Using the high-quality bond valence parameters r0 = 2.370 Å and b = 0.37 Å reported
for In3+ – S chemical bonds and covalent radii determined for In, Sn and Ge, it has been established
that: (i) the subsulfide In5S4 does not exist; (ii) the oxidation state of Indium in the MIn4S4 (M – Sn,
Ge) compounds is definitely +3; while (iii) the oxidation states of Tin and Germanium in the MIn4S4
(M – Sn, Ge) compounds are –4.
