Abstract
The study shows that in the structure of davyne from the Baikal region sulfur exists in two forms: sulfate and sulfide. The presence of disulfide makes it possible to remove charge imbalance in the chemical formula that emerged mainly because all sulfur was presented in the mineral only in the sulfate form. So far, sulfide sulfur has not been observed in the minerals of the davyne subgroup.
