2.23 Si-N键长(1.93-1.96 nm),除桥氮外,每个硅原子相对于它和所连接的C和Fe原子几乎是平面几何结构。1的结构和光谱数据表明,Fe-Si键具有部分双键特征(双硅烯结构),而Si-N键则是共价键和弱配价键的混合键。
2.23 Á), fairly long Si—N bonds (1.93-1.96 Á), and almost planar geometry at each silicon atom with respect to it and the attached C and Fe atoms, excluding the bridging nitrogen. These structural and spectroscopic data for 1 strongly indicate that the Fe—Si bonds take on partial double-bond character (bis (silylene) structure), while the Si—N bonds can be described as a hybrid of a covalent and weak dative bond.
