In this paper are reported Acen and Salean complexes of the Group 13 elements in a ligand-to-metal stoichiometry of 1:2. These are unconventional by comparison to previously reported examples (with these ligands ) which are predominantly of a 1:1 and 1:3 stoichiometry. The Acen complex, Acen (BPh2)2 (1) (where AcenH2 is N,N'- bis (2-hydroxy(methyl) benzylidene ) ethylenediamine ('common' name)) was isolated as a minor side-product in the synthesis of [ AcenAl ( MeOH )2] BPh4. In a different type of reaction the monomeric SaleanHAl (Al(NMe2)3) (2) (where SaleanH4 is N,N'-bis(2-hydroxybenzy1) ethylenediamine ('common' name)) is isolated. Crystal data for (1): triclinic, Pī , a 9.701(3), b 11.116(1), c 11.393(2) Ǻ, α 62.84(1), β 78.99(1), γ 79.94(1)°, V 1067.6(4), Z 21 with 1032 reflections with F > 6.0σ(F), R = 0.0725. Crystal data for (2): orthorhombic, P 212121, a 12.432(3), b 12.574(2), c 20.024(4) Ǻ, V 3130.3(11), Z 4, with 855 reflections with F > 5.0σ(F), R=0.1044.
本文报告了配体与金属配比为 1:2 的第 13 族元素的 Acen 和 Salean 复合物。与之前报道的主要为 1:1 和 1:3 配位比的例子(使用这些配体)相比,这些配合物是非常规的。Acen 复合物 Acen (BPh2)2 (1) (其中 AcenH2 是 N,N'-双(2-羟基(甲基)亚苄基)乙二胺("通用 "名称))是在合成 [ AcenAl ( MeOH )2] BPh4 的过程中作为次要副产品分离出来的。在另一种反应中,分离出了单体 SaleanHAl (Al(NMe2)3) (2)(其中 SaleanH4 是 N,N'-双(2-羟基苄基)乙二胺("通用 "名称))。(1) 的晶体数据:三棱,Pī ,a 9.701(3),b 11.116(1),c 11.393(2) Ǻ,α 62.84(1),β 78.99(1),γ 79.94(1)°,V 1067.6(4),Z 21,1032 次反射,F > 6.0σ(F),R = 0.0725。(2)的晶体数据:正交,P 212121,a 12.432(3),b 12.574(2),c 20.024(4)Ǻ,V 3130.3(11),Z 4,具有 855 个 F >5.0σ(F)反射,R=0.1044。
