Synthesis, characterization and experimental study of three new bridged tin(IV)‎ coordination complexes with dithiocarbamates

الملخص EN

Sodium (1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)carbamodithioate (L) react with dimethyltin dichloride R2SnC12 (R = methyl (2a), R=n-Bu (2b) and R = Ph (2c)) to produce the new tin adducts R2SnCIL (3a-c) in good yields.

structures of these complexes were established by IR, IH, 13C and 119Sn NMR spectroscopic, and elemental analyses data.

the 119Sn NMR analyses in solution revealed an absolute tetra coordinate for Mc2SnC12 derivative, whereas, in the case of n-Bu2SnC12 and Ph2SnC12 derivatives, five coordination species were exclusively observed.
