A new compound EnrH3[SnBr3.46Cl2.54]⋅H2O, where EnrH32+ is the enrofloxacinium cation (C19H24FN3O32+), is synthesized and its crystal and molecular structure is determined. Crystallographic data for enrofloxacinium tetrabromidodichloridostannate(IV) monohydrate are as follows: a = 17.1262(19) Å, b = 10.3435(11) Å, c = 17.2582(19) Å, β = 119.203(1)°, V = 2640.5(4) Å3, space group P21/c, Z = 4. Hydrogen bonds form a branched three-dimensional network linking EnrH32+, [SnBr3.46Cl2.54]2–, and water molecules. The structure is also stabilized by the π–π interaction of EnrH32+ aromatic rings.
