Synthesis and Crystal Structure of Trimecaine Hexachlorostannate(IV) Monohydrate

Single-crystals of trimecaine (2-diethylamino-N-(2,4,6-trimethylphenyl)acetamide, Tm) hydrochloride monohydrate and its newly synthesized hexachlorostannate(IV) monohydrate have been prepared and characterized by X-ray diffraction analyses. Tm.HCl.H2O crystallizes in the rhombic space group Paac with a = 28.999(5), b = 11.190(3), c = 10.573(3) Å, and Z = 8, forming crystal structure, in which TmH+ ions are united in infinite chains by intermolecular NH...Cl...HN bonds, while water molecules connect chains by OH...Cl...HO bonds. (TmH)2[SnCl6].H2O crystallizes in the rhombic space group P212121 with a = 10.745(1), b = 14.199(2), c = 26.166(3) Å, and Z = 4, forming structure of molecular crystal with distorted SnCl62– octahedrons asymmetrically associated with water molecule and two TmH+ ions by two Cl...HO, O...HN, and bifurcated NH...2Cl hydrogen bonds.
