C-organostannyl- and organosilyl-derivatives of 2-(thien-2-ylmethyl)thiophene and 1-[(1H-pyrazol-1-yl)methyl]-1H-pyrazole have been synthesised and characterised spectroscopically. Lithiation and subsequent substitution by R3M takes place at the 5,5' positions for both bis-heterocycles, and this is confirmed by the X-ray structure of 1,1'-[5,5'-(Ph3Sn)C3N2](2)CH2.
