二正丁基锡水杨醛缩对氨基苯甲酸酯配合物的合成、表征及结构研究

The title complex {[ⁿBu₂Sn(2-OHC₆H₄CH=NC₆H₄COO)]₂O}₂·2H₂O was synthesized by the reaction of N-(4-carboxyphenyl)-salicylideneimine with dibutyltin(IV) oxide in 1∶1 molar ratio. The compound has been characterized by elemental analysis, IR, ¹H NMR spectra and X-ray single crystal diffraction. It crystallizes in triclinic system with space group P1. The crystal data are: a=1.242 9(2) nm, b=1.261 3(2) nm, c=1.594 9(3) nm, α=102.06(2)°, β=92.884(3)°, γ=95.939(3)°, Z=2, D_c=1.342 g·cm^-3, F(000)=1 000, V=2.425 2(7) nm³, R₁=0.041 5, wR₂=0.104 4. The compound is in centro-symmetric dimer structure mode with a four-member central endo-cyclic Sn₂O₂ unit in which the bridging oxygen atoms are tri-coordinated. All the tin atoms are five-coordinated with geometry of distorted trigonal bipyramid. CCDC:286105.
