The reaction of the amidinato silylsilylene with a functionalized diaminochlorosilyl substituent, [LSiSi(Cl){(NtBu)2C(H)Ph}] (1; L = PhC(NtBu)2), with ArN═C═NAr (Ar = 2,6-iPr2C6H3) in toluene afforded the delocalized hypervalent silyl radical [LSi•(μ-CNAr)2Si{(NtBu)2C(H)Ph}] (2). It possesses a hypervalent silyl radical that delocalizes throughout the Si2C2 ring.
