Molecular formulas for non-stoichiometric compounds often feature decimal subscripts to represent variable elemental compositions.

The analysis

The claim states that molecular formulas can contain decimal subscripts in non-stoichiometric compounds. Paper [1] discusses the chemistry of non-stoichiometric compounds, and Paper [7] explicitly uses a fractional/decimal subscript in the formula Cu_xV_2O_5 to denote non-stoichiometric insertion. Therefore, the claim is supported.
