Synthesis, Spectral (FT‐IR, ¹H, ¹³C, ¹¹⁹Sn) and Biological Studies of Bimetallic Trimethyltin(IV) Germapropionates: X‐Ray Structure of (CH₃)₃Sn(C₂₂H₂₁O₂Ge)

New compounds of bimetallic trimethyltin(IV) germapropionates have been synthesized and characterized by elemental analyses, FT‐IR, and multinuclear nmr (¹H,¹³C,¹¹⁹Sn) spectroscopies. These compounds show four‐coordinated structure in solution and penta‐coordinated structure in solid state. The crystal structure of representative compound, (CH₃)₃Sn(C₂₂ H₂₁ O₂ Ge), shows one dimensional polymeric penta‐coordinated structure in its solid state. The synthesized compounds were subjected for a bioassay screening and show promising antibacterial and antifungal activitie.
