N2 - The first solid state 29Si NMR of a disilyne, that is, RSiSiR, R = Si(CH(SiMe3)2)2(i-Pr) (1) was measured: δ11 = 364 ± 20; δ22 = 221 ± 16 and δ33 = -350 ± 13; CSA = -643 ppm. These measured values as well as calculations for model disilynes strongly support the description of the Si-Si bond in bent disilynes as a triple bond, although with weakened π-bonds and a reduced bond order of 2.6.
