【摘要】 利用溶剂热的方法将Cp2TiCl2(Cp=η5-C5H5)与2,6-吡啶二羧酸钠(L)反应,不同的反应时间得到了2个具有不同晶体空间群的化合物Cp2TiL(1a和1b),而在常温或低温下,Cp2TiCl2或CpTiCl3同羧酸盐或亚胺反应却得到了双核或四核氧桥联的钛化合物。更多还原

【Abstract】 Four titanium complexes of Cp2TiL (1a and 1b), Cp2Ti2Cl2( μ-O) (2), Cp4Ti4Cl4( μ-O)4 (3) (Cp=η5-C5H5, L=2,6-dipicolinate) have been synthesized and structurally characterized by X-ray diffraction single crystal structural analysis. The crystal structure of complex 1a has the same chemical formula and different space group with that of complex of 1b. The molecule of 2 or 3 has a dimeric or tetrameric structure connected by a μ-O ligand, respectively, and the titanium atoms are surrounded by one Cl atom and one O atom. CCDC: 609318, 1a; 609319, 1b; 609320, 2; 609321, 3.更多还原
