二维层状二- μ2-羟基二乙酸-二- μ3-氧八丁基四锡的合成、晶体结构及杀菌活性

The complex 1, [systematic name 1,2,3,4-di-μ₂-hydroxyl-1,4-diacetic-1,1,2,2,3,3,4,4-octa-n-butyl-di-μ₃-oxo-tetratin(Ⅳ)], [Sn₄(C₆H₅)₈(OH)₂O₂(CH₃COO)₂], was synthesized and characterized by elemental analysis, ¹H NMR, FTIR spectroscopy and X-ray diffraction single crystal struscture analysis. The symmetric dimer with a hydroxy bridged ladder consists of a central Sn₂O₂ ring with two additional adjacent Sn₂(OH)O four-membered rings. The Sn, O and OH atoms are approximately coplanar; the Sn atoms exhibit a distorted trigonal-bipyramidal coordination configuration. The 2D layer is exhibited with chanels formed by the hydrogen-bonded (C-H…O). The antibacterial activity was preliminarily studied. CCDC: 666441.
