• Tin complexes of alkoxy functionalized oxime ligands were synthesized.
• X-ray analysis confirms dimeric structures.
• Metal centers were bridged by μ2-O bonds.
• Tin metal centers in complexes exhibit unusual square pyramidal geometry.
Novel tin complexes stabilized by alkoxy-functionalized oxime ligands [Sn(L1)2]2 (1) and [Sn(L2)2]2 (2), were prepared and characterized. Single-crystal X-ray diffraction analysis revealed that the complexes were obtained as dimers in which the tin metal centers are bridged by a pair of μ2-oxygen atoms. Due to the ligand steric effects, the metal centers in these complexes adopted an unusual distorted square pyramidal geometry and displayed interesting structural features. The thermo-gravimetric analyses of the complexes showed major mass loss in the 175–380 °C region.
Syntheses of new tin complexes stabilized by alkoxy functionalized oxime ligands were demonstrated. These complexes exhibit interesting structural features because of their dimeric structures and display μ2-O bonding between metal centers. These tin–oxime complexes were studied as potential strontium precursor for thin film applications.Figure optionsDownload as PowerPoint slide
