Structure of the Oxonium Compound of Pefloxacinium Hexachloridostannate(IV)

The structure of tris{hexachloridostannate(IV)}-hexachloride-tetrakis(pefloxacinium)-tetraoxonium undecahydrate (CCDC 1551760) 4PefH ₃ ²⁺ , 4H₃O⁺, 3SnCl ₆ ²⁻ , 6Cl⁻, 11H₂O (I), (PefH is pefloxacin) is determined. The I crystals are triclinic: a = 13.5474(10) Å, b = 15.2859(11) Å, c = 15.6586(11) Å, α = 94.467(1)°, β = 105.477(1)°, γ = 111.560(1)°, V = 2849.9(4) ų, space group Pī, Z = 1. The structure is stabilized by multiple intermolecular hydrogen bonds and π–π-interactions between the PefH₃²⁺ ions.
