摘要
Mn[2- nme2 -α-SiMeC6H4]2 (I)是三斜的，P1。203 K时的晶胞尺寸为a=9.318(2) a, b=10.781(3) a, c=13.453(3) a， α=88.87(3)°，β=88.34(3)°，γ=76.91(2)°，V=1315.8(6)A3, Dx =1.181 g/cm3, Z = 2。对于I > 2σ(I)的3442个实测反射，最终R值为0.072。该结构由MnCl2与2-二甲氨基- r -三甲基硅基苄基li反应合成。中心金属Mn(II)通过形成一个扭曲的四面体具有四个配位位点。
Synthesis and Structural Characterization of Bis[2-dimethylamino-α-trimethylsilylbenzyl]Mn(II)
Mn[2-NMe2-α-SiMeC6H4]2 (I) is triclinic, P1. The unit-cell dimensions at 203 K are a=9.318(2)A, b=10.781(3)A, c=13.453(3)A, α=88.87(3)°, β=88.34(3)°, γ=76.91(2)°, V=1315.8(6)A3, Dx =1.181 g/cm3, and Z = 2. The final R value is 0.072 for 3442 measured reflections with I > 2σ(I). The structure is synthesized by the reaction of MnCl2 with 2-dimethylamino-R-trimethylsilylbenzyl-Li. The central Mn(II) metal has four coordination sites by forming a distorted tetrahedron.
