Fluoroquinolone compounds with the composition CfH2+2CfH22+, 2Cl–, H2O (CfH2Cl2·H2O (I)) and 4LevoH2+24LevoH22+, 3[SnCl6]2–, 2Cl–, 2H2O ((LevoH2)4[SnCl6]3Cl2·2H2O (II)) (Cf is ciprofloxacin, Levo is levofloxacin) are prepared. Their structures are determined by XRSCD. Crystals I are monoclinic: a = 8.6389(11) Å, b = 14.5486(19) Å, c = 14.8605(19) Å, β = 91.914(3)°, V = 1866.7(4) Å3, space group P21/c, Z = 4. Crystals II are triclinic: a = 12.4821(8) Å, b = 13.8144(8) Å, c = 15.2342(9) Å, α = 84.360(1)°, β = 79.265(1)°, γ = 74.038(1)°, V = 2478.3(3) Å3, space group P1, Z = 1. The structures are stabilized by multiple hydrogen bonds. The photoluminescent properties and thermal stability of compound I are considered.
