The vibrational spectra of the three (amino)monohalogenosilanes show dramitic changes on solidification, but those of the (amino)dichlorosilane are very similar in all three phases. These differences are discussed in the light of the formation of dimers in the crystalline solid of SiH2Cl(NMe2), and the presence of discrete monomers in the crystal of SiHCl2(NMe2). The n.m.r. spectra of the compounds
我们已经制备并表征了新化合物SiH 2 Cl(NMe 2),SiH 2 Br(NMe 2),SiH 2 I(NMe 2)和SiHCl 2(NMe 2)。三种(氨基)单卤代硅烷的振动光谱显示出固化时的剧烈变化,但(氨基)二氯硅烷的振动光谱在所有三个阶段中都非常相似。根据SiH 2 Cl(NMe 2)晶体固体中二聚体的形成以及SiHCl 2(NMe 2)晶体中离散单体的存在,对这些差异进行了讨论。)。报道并简要讨论了该化合物以及单氟硅烷SiH 2 F(NMe 2)的nmr光谱。
