- Abstract
A new series of diorganotin complexes of the type R2SnL (L1: N-(2-hydroxy-5-chlorophenyl)- 3-ethoxysalicylideneimine, R = Me, (Me2SnL1), R = n-Bu, ( n-Bu2SnL1), R = Ph, (Ph2SnL1), L2: N-(2-hydroxy-4-nitro-5-chlorophenyl)-3-ethoxysalicylideneimine, R = Ph, Ph2SnL2, L3: N-(2-hydroxy-4-nitrophenyl)-3-methoxysalicylideneimine, R = Me, (Me2SnL3), R = n-Bu, ( n-Bu2SnL3), L4: N-(2-hydroxy-4-nitrophenyl)-3-ethoxysalicylideneimine, R = Me, (Me2SnL4), R = n-Bu, ( n-Bu2SnL4)) were synthesized and characterized by elemental analysis, infrared (IR), 1H, and 13C NMR mass spectroscopic techniques, and electrochemical measurements. Ph2SnL1 and Ph2SnL2 were also characterized by X-ray diffraction analysis and were found to show a fivefold C2NO2 coordination geometry nearly halfway between a trigonal bipyramidal and distorted square pyramidal arrangement. The CSnC angles in the complexes were calculated using Lockhart's equations with the 1J(117/119Sn-13C) and 2J(117/119Sn-1H) values from the 1H NMR and 13C NMR spectra. Biocidal activity tests against several micro-organisms and some fungi indicate that all the complexes are mildly active against Gram (+) bacteria and the fungi, A. niger and inactive against Gram (−) bacteria. © 2010 Wiley Periodicals, Inc.
