Abstract
New organotin(IV) compounds containing the carboxylate ligand 2,3-methylenedioxybenzoic acid (
HL
) have been synthesized with the general formula R
2
SnL
2
(R = Me, Et,
n
-Bu, Ph and
n
-Oct) and R
3
SnL (R =
n
-Bu). All compounds have been studied in the solution state by multinuclear NMR (
1
H,
13
C and
119
Sn) by using the non-coordinating solvent and also in solid sate by FTIR, mass spectrometry and X-ray crystallography. Spectroscopic data have shown that methylenedioxy moiety does not coordinate with tin atom and the coordination site is actually -COO group, as is proved by X-ray structure determination. The solid state structure of compound (
2
) has been determined by X-ray crystallography which shows that the complex (
2
) has distorted octahedral geometry. These complexes have been evaluated
in vitro
against crown gall tumor and antibacterial activity. Interesting results were noticed during the bio-activity screenings, which proved their
in vitro
biological potential and possible use as drugs.
