Synthesis and Structural Characterization of Bis[2-dimethylamino-α-trimethylsilylbenzyl]Mn(II)

Abstract

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.
