The molecular structures of methylbis(methylsilyl)amine, NMe(SiH2Me)2, and bis(dimethylsilyl)methylamine, NMe(SiHMe2)2, in the gas phase have been determined by electron diffraction.In both molecules the NCSi2 skeleton is planar.Principal parameters (ra) for NMe(SiH2Me)2 are: r(Si-N) 171.8(3), r(Si-C) 186.4(5), r(C-N) 149.2(12) pm; Si-N-Si 125.6(10) and N-Si-C 113.5(18) deg and for NMe(SiHMe2)2 are: r(Si-N) 172.7(4), r(Si-C) 187.2(3), r(C-N) 148.3(7) pm; Si-N-Si 126.1(5), N-Si-C 110.8(5), and C-Si-C 115.5(10) deg.In NMe(SiH2Me)2 the SiH2Me groups are twisted about 60 and 120 deg from the positions in which the Si-C bonds eclipse the N-C bond, so that the methyl groups are mutually trans when viewed along the Si...Si axis.In NMe(SiHMe2)2 the SiHMe2 groups are twisted 20 and 120 deg from positions in which the Si-H bonds are trans to the N-C bond.
