(a) Two-dimensional ([Sn₅F₂₄]⁴⁻)_∞ grids with a wave-like conformation and the [XeF₅]⁺ cations located between them in the crystal structure of [XeF₅]₄[Sn₅F₂₄]. For clarity, the [XeF₅]⁺ cations are presented with sticks only; (b) The ([Sn₅F₂₄]⁴⁻)_∞ layer in the crystal structure of [XeF₅]₄[Sn₅F₂₄] contains both six- and seven-coordinated Sn(IV) interconnected by bridging fluorine atoms (view perpendicular to the layer, along the a-axis).
