Synthesis and Crystal Structure of 3-Methoxycarbonylethyltin tetrachlorides Anion
【摘要】 在用酯基锡MeO2CCH2CH2SnCl3合成配合物MeO2CCH2CH2SnCl3·(2-OHC6H4CH=NC6H5)时,其配合物的甲苯溶液放置培养单晶时(放置十天以上)会发生分解生成配合物MeO2CCH2CH2SnCl4—·H+。研究了标题化合物的合成反应,用元素分析、IR、NMR对配合物进行了表征,并测定了晶体结构。为正交晶系,空间群为P2cn, a=7.852(2), b=12.236(1), c=16.952(4) ? V=1628.7?, Z=4, Dc=1.79g/cm3, F(000)= 860,m=22.2cm—1(Mo),R=0.0449, Rw=0.0382。标题化合物的空间构型为畸变的八面体构型,中心锡原子的配位数为6。
【Abstract】 The anion of MeO2CCH2CH2SnCl4- was obtained by decomposing the yellow solution of MeO2CCH2CH2SnCl3?2-OHC6H4CH=NC6H5) by standing for 15 days, which is the product of 3-methoxy-carbonylethyltin trichlorides with Schiff base (2-OHC6H4CH=NC6H5).The title compound was characterized by elemental analysis, IR, 1H NMR,13C NMR and X-ray diffraction analysis . The crystal of the title compound belongs to orthorhombic system, space group P2cn, a=7.852(2),b=12.236(1), c=16.952(4) A°,V=1628.7 ?, Z=4, Dc=1.79g/cm3, F(000)= 860,m=22.2cm-1 , R=0.0449, Rw=0.0382 . The title compound exists as a discrete molecule, and the tin atom attains a distorted octahedral geometry via the coordination of intramolecular carbonyl oxygen and chloride ion. The coordination number of tin atom is 6.
