novel exchange between a Cl and an NMe2 group, yielding the product [TiCl3(NMe2)(μ-NMe2)2AsCl]. The crystal structure of [TiCl3(NMe2)(μ-NMe2)2AsCl] has been determined and showed that the titanium and arsenic atoms are linked via two bridging NMe2 groups. Additionally, crystal structures for the 1 : 1 and 1 : 2 adducts, [TiCl4(AsPh3)] and [TiCl4(AsPh3)2] have been obtained, with Ti–As bond lengths of

钛a化合物是通过以下反应合成的的TiCl 4 和 AsPh 3(1:1和1:2当量),或Ph 2 AsCH 2 AsPh 2,t BuAsH 2和
砷(NMe 2)3。通常,[类型的1:1和1:2加合物TiCl 4(L)n](n = 1,L =AsPh 3,Ph 2 AsCH 2 AsPh 2和t BuAsH 2 ; n = 2,L =AsPh 3),进行了隔离和表征。但是,的TiCl 4 和
砷(NMe 2)3导致Cl和NMe 2基团之间发生了新颖的交换,从而产生了[的TiCl 3(NME 2)(μ-NME 2)2 AscI位]。[的晶体结构的TiCl 3(NME 2)(μ-NME 2)2 AscI位]已确定,并表明
