  Synthesis, spectroscopic investigations, crystal structures and antibacterial activity of 3-(3-hydroxypyridin-2-ylamino)-1-phenylbut-2-en-1-one and its diorganotin(IV) complexes

  摘要：

  Two new organotin(IV) complexes, [SnPh2(L)] (1) and [SnMe2(L)] (2), have been synthesized from the reaction of SnPh2Cl2 and SnMe2Cl2 with a Schiff base, 3-(3-hydroxypyridin-2-ylamino)-1-phenylbut-2en-1-one (H2L), derived from 2-amino-3-hydroxypyridine and benzoylacetone. The new compounds have been characterized by elemental analysis, FT-IR, H-1 and Sn-119 NMR spectroscopy. The structures of H2L and 2 have been confirmed by X-ray crystallography. Crystals of H2L are orthorhombic with the space group P2(1)2(1)2(1). This compound forms a dimer in the solid state which is held together by two intermolecular hydrogen bonds. This Schiff base exists as the keto-amine tautomeric form with one intramolecular N-H center dot center dot center dot O hydrogen bond. In the two complexes the Schiff base is completely deprotonated and coordinates to tin as tridentate via the imine nitrogen and phenolic and enolic oxygen atoms, and the coordination number of the tin center is five. Complex 2 crystallizes in the monoclinic space group, P2(1)/n, and the structure is distorted square pyramidal, with the imine nitrogen in the apical position. The in vitro antibacterial activity of the Schiff base and its complexes has been evaluated against Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria. H2L showed no activity, but the organotin(IV) complexes exhibited good activities along with the standard antibacterial drugs. (C) 2011 Elsevier Ltd. All rights reserved.
