2. Oxygen and sulfur form a number of binary fluorides. (Answer in English)

(c) Disulfur difluoride, S₂F₂, exists as two structural isomers. One isomer is analogous in structure to dioxygen difluoride, O₂F₂, but the second, more thermodynamically stable isomer, has a structure in which the two sulfur atoms are in different chemical environments. Draw a Lewis structure of the more stable isomer of disulfur difluoride, S₂F₂, and sketch or describe its three-dimensional shape.
