The diaminosilylene tBuNCH(2)CH(2)NtBuSi: reacted with the diaminogerm
ylenes RNCH2CH2NRGe: R = 2,6-Me2C6H3, iPr, by silylene insertion into
one of the Ge-N bonds to furnish the aminosilylgermylenes 8, R = 2,6-M
e2C6H3, and 9, R = iPr. The X-ray structure analyses of these compound
s revealed that 8 remains monomeric in the crystal with weak Ge Ge int
eractions to the germanium atom of a neighbouring germylene molecule,
whereas 9 dimerizes to give the strongly twisted (E)-1,2-diamino-1,2-d
isilyldigermene (E)-10 with a long Ge-Ge double bond of 246 pm and a l
arge trans-bent angle of 47.3 degrees.
