Di- n -butyltin(IV) 2,6-pyridinedicarboxylate [(2,6-CO 2 ) 2 C 5 H 3 NSnBu 2 (H 2 O)] 2 ·CHCl 3 , has been synthesized and characterized by elemental analyses, infrared and NMR ( 1 H and 13 C) spectroscopy, and single-crystal X-ray diffraction. The title complex crystallizes in the triclinic space group P1‾$P‾{1}$; with a = 9.2330(4), b = 10.4790(5), c = 20.2489(8) Å, α = 89.439(4), β = 87.492(3), γ = 85.888(4)°, V = 1951.96(15) Å 3 , and Z = 2. In this complex, the 2,6-pyridinedicarboxylate groups are tetradentate, chelating, and bridging ligands for the tin(IV) atoms. NMR spectra showed that the ligands bind to the tin(IV) center in the anionic (COO − ) form. In the asymmetric unit of the dimeric complex, the monomer is composed of an n -Bu 2 Sn unit bonded to one 2,6-pyridinedicarboxylate group through one nitrogen and two oxygen donor atoms. It is also coordinated by a water molecule. In the dimer formed by carboxylate bridging, a trans- heptacoordinated geometry around the tin(IV) atom is established. The chloroform molecule is connected to the dimer by C–H···O contacts. Compound exhibits extended O–H···O and C–H···O hydrogen bonding networks leading to a supramolecular layer topology.

[(2,6-CO2)2C5H3NSnBu2(H2O)] 2·CHCl3的合成,光谱(FT-IR,1H,13C)研究和晶体结构
2,6-吡啶二羧酸二正丁基锡(IV)[(2,6-CO 2)2 C 5 H 3 NSnBu 2(H 2 O)] 2·CHCl 3的合成和红外元素分析表征NMR(1 H和13 C)光谱,以及单晶X射线衍射。标题复合体在三斜空间群P1‾ $ P‾ {1} $;中结晶。其中a = 9.2330(4),b = 10.4790(5),c = 20.2489(8)Å,α= 89.439(4),β= 87.492(3),γ= 85.888(4)°,V = 1951.96(15 )Å3,Z =2。在该络合物中,2,6-吡啶二羧酸酯基团是锡(IV)原子的四齿,螯合和桥联配体。NMR光谱表明,配体以阴离子(COO-)的形式结合到锡(IV)中心。在二聚体络合物的不对称单元中,单体由键合到一个2的n -Bu 2 Sn单元组成 通过一个氮原子和两个氧供体原子的6-吡啶二羧酸酯基团。它也由水分子协调。在通过羧酸盐桥联形成的二聚体中,围绕锡(IV)原子建立了超庚配位的几何形状。氯仿分子通过C–H···O触点连接至二聚体。化合物表现出扩展的OH···O和CH···O氢键网络,导致超分子层拓扑。
