The interaction of organotin(iv) acceptors with 1,4-bis(5-hydroxy-1-phenyl-3-methyl-1H-pyrazol-4-yl)butane-1,4-dioneCoordination chemistry of bis(pyrazolones): a rational design of nuclearity tailored polynuclear complexes. Part 2.22
From the interaction of organotin(IV) halides SnR2Cl2 with 1,4-bis(5-hydroxy-1-phenyl-3-methyl-1H-pyrazol-4-yl)butane-1,4-dione (Q2QH2) in methanol in the presence of base the complexes [SnR2(Q2Q)] (1: R = isobutyl (Bui); 2: R = n-octyl (Ot); 3: R = n-dodecyl (Do)) have been synthesised. The reaction between equimolar quantities of R2SnO and Q2QH2 in toluene yields the dinuclear derivatives [SnR2(Q2Q)]24

C−Sn−C of 151.5(5)°. Each ligandchelates the metal with different donor abilities [Sn−O bond lengths of 2.423(8) A and 2.135(8) A in one ligand, and 2.107(9) A and 2.357(8) A in the other]; results for the 2nd molecule are similar. The coordination arrangement differs from those of relatedbis(β-diketonato)diorganotin derivatives containing asymmetric ligands, which are characterized by an approximate
合成了 β-二酮基苯甲酰丙酮基配体的二有机锡 (IV) 配合物,并用 IR 和多核 (H, C, Sn) NMR 光谱对其进行了表征。双(苯甲酰丙酮)二叔丁基锡 (IV) 的 X 射线衍射研究显示晶胞中有两个独立的分子。金属多面体是一个扭曲的八面体(斜梯形双锥体),其跨角 C−Sn−C 为 151.5(5)°。每个配体以不同的供体能力螯合金属[一个配体中的 Sn-O 键长为 2.423(8) A 和 2.135(8) A,另一个配体中为 2.107(9) A 和 2.357(8) A];第二个分子的结果是相似的。配位排列不同于含有不对称配体的相关双(β-二酮)二有机锡衍生物,其特征在于近似 Cs 对称性,因为两个苯甲酰丙酮配体都将它们的甲基(和苯基)取代基指向(反)金属原子。观察到螯合物平面性和一些苯基螯合物共平面性。Hartree-Fock (HF) 和密度泛函理论 (DFT) 计算的结构与使用
