M. Ashfaq et al., Organotin esters of N-phthaloylamino acids: Synthesis, spectroscopic characterization, and biological activities, B CHEM S J, 72(9), 1999, pp. 2073-2078
The synthesis, physical nature and spectroscopic characterization, i.e. CHN
analyses as well as the IR, H-1-, C-13-, Sn-119 NMR and Sn-119m Mossbauer
spectrometries, of a series of new organotin complexes of N-phthaloylamino
acids are described. The monomeric diorganotin complexes possess a trans oc
tahedral geometry. The dimeric tetraorganotin complexes have a penta-coordi
nate environment. The triphenyltin with N-phthaloylamino acids are assigned
a polymeric trigonal bipyramidal geometry in the solid form and a tetrahed
ral structure in an inert solvent, while tricyclohexyltin with N-phthaloyla
mino acids complexes possess a tetrahedral geometry. ED50 and biological ac
tivities tests were also carried out, which indicated powerful biocidal eff
ects.
