利用三丁基氯化锡和2-吡啶甲酸在三乙胺存在下以1:1摩尔比反应,合成了非预期有机锡配合物[(n-C_4H_9)_2Sn(2-PyCO_2)_2(H_2O)].通过元素分析、红外光谱、核磁共振氢谱和X-射线单晶衍射对其结构进行了表征.测试结果表明,该配合物为单体结构,锡原子呈七配位畸变五角双锥构型.通过配位水分子和游离羰基氧原子的氢键作用,形成了二维网状结构.
The unplanned organotin complex [(n-C_4H_9) _2Sn (2-PyCO_2) _2 (H_2O)] was synthesized by the reaction of tributyltin chloride with 2-picolinic acid in the presence of triethylamine at a molar ratio of 1: ] .The structure was characterized by elemental analysis, IR, 1HNMR and X-ray single crystal diffraction.The results showed that the complex was a single crystal structure and the tin atom showed a seven-coordinate distortion pentagonal double cone structure The two-dimensional network structure is formed by the hydrogen bond between coordinated water molecules and free carbonyl oxygen atoms.
