Diorganotin(IV) complexes of 3,5-dichloro-2-hydroxybenzaldehyde-N(4)-ethylthiosemicarbazone: Synthesis, spectral characterization and crystal structure

Synthesis, characterisation and biological activity of diorganotin compounds of (E)-N'-(5-nitro-2-hydroxybenzylidene)-3-hydroxy-2-naphthohydrazide

“…Meanwhile, another strong stretching band emerges around 1600 cm -1 suggesting the involvement of the azomethine-N atom in coordination to the tin atom, thus weakening the C=N bond and leading to the formation of the ν(C=N-N=C) fragment. The ν(Sn-O) and ν(Sn-N) bands are observed in the regions 690-710 and 460-480 cm -1 , respectively[53][54][55].…”
