Sn(SiMe3)3 (1) or Si(SiMe3)3 (2)] and divalent Ge [Ge(2-(Me3Si)2C}-C5H4N)R] [R = Cl (3) or CH(PPh2)2 (4)] have been prepared and characterized, and their molecular structures were determined by single-crystal X-ray diffraction. The stannylenes 1 and 2 were prepared from the corresponding heteroleptic chloro-analogue, [Sn(2-(Me3Si)2C}-C5H4N)Cl]; 1 is the first structurally characterized compound to contain
