structural aspects of the products isolated from the reactions of a series of titanium alkoxides [[Ti(OR)4]n n = 2, OR = OCH2C(CH3)3 (ONep) (1); n = 1, OC6H3(CH3)2-2,6 (DMP) (2)] with rubidium alkoxides [[Rb(OR)]infinity where OR = (ONep) (3), (DMP) (4), and OC6H3(CH(CH3)2)2-2,6 (DIP) (5)]. The resultant doublealkoxides were determined by single crystal X-ray diffraction to be [Rb(mu-ONep)4(py)Ti(ONep)]2
本报告研究了从一系列钛醇盐[[Ti(OR)4] nn = 2,或= OCH2C(CH3)3(ONep)(1)的反应中分离出的产物的结构方面。n = 1,OC6H3(CH3)2-2,6(DMP)(2)]与rub的醇盐[[Rb(OR)]无穷大,其中OR =(ONep)(3),(DMP)(4)和OC6H3 (CH(CH3)2)2-2,6(DIP)(5)]。通过单晶X射线衍射确定所得的双醇盐为[Rb(mu-ONep)4(py)Ti(ONep)] 2(6),[Rb(mu-DMP)Ti(DMP)4]无穷大(7)和[Rb(mu-DMP)2(mu-ONep)2Ti(ONep)]无穷大(8)。化合物1是先前报道的具有三角双锥体Ti金属中心的小分子物种,而化合物2是具有四面体Ti中心的单体。没有分离出合适的X射线质量为3的晶体。化合物4和5证明了利用末端mu-和mu3-OR配体以及相邻OAr配体的pi相互作用
