Three m-terphenyl ligands 2,6-Ar2C6H3(-) [Ar = 2,6-Me2C6H3 (2,6-Xyl); 3,5-Me2C6H3 (3,5-Xyl); 2,3,4,5,6-Me5C6 (Pmp)] have been used to stabilise three series of two-coordinate Group 12 diaryl complexes; (2,6-Ar2C6H3)2M [M = Zn, Cd, Hg, Ar = 2,6-Xyl 1-3, 3,5-Xyl 4-6, Pmp 7-9], where differing steric demands on the metal centres are imparted. These are the first homoleptic d-block complexes featuring any of these ligands. Complexes 1-9 have been characterised in solution and the solid state; the analysis of structural changes produced by differences in ligand properties is reported. In particular, complexes 4-6 show smaller C-M-C bond angles and contain secondary ligand interactions that are not seen in the analogous complexes 1-3 and 7-9.
三种间三联苯配体2,6 - Ar₂C₆H₃⁻ [Ar = 2,6 - Me₂C₆H₃ (2,6 - 二甲基苯基); 3,5 - Me₂C₆H₃ (3,5 - 二甲基苯基); 2,3,4,5,6 - Me₅C₆ (戊甲基苯基)] 已被用于稳定三类二配位第12族二芳基配合物；(2,6 - Ar₂C₆H₃)₂M [M = Zn、Cd、Hg，Ar = 2,6 - 二甲基苯基 1 - 3，3,5 - 二甲基苯基 4 - 6，戊甲基苯基 7 - 9]，其中对金属中心施加了不同的空间需求。这些是首批含有这些配体中任何一种的同配d区配合物。配合物1 - 9已在溶液和固态中进行了表征；报告了对由配体性质差异产生的结构变化的分析。特别地，配合物4 - 6显示出较小的C - M - C键角，并且包含在类似的配合物1 - 3和7 - 9中未观察到的二级配体相互作用。
