First reductive dimerization of a polycyclic azine.
The tptz molecule is reduced by potassium into its anion-radical in the compound K(tptz)(2) (), whereas it is reductively coupled by SmI(2) and UI(3)(py)(4) into the bis-triazinide ligand in the dinuclear complexes [Sm(2)(tptz-tptz)(DMF)(8)][I](4).3.5DMF (.3.5DMF) and U(2)I(6)(tptz-tptz)(MeCN)(2).2MeCN (.2MeCN) where each metal ion occupies a pentadentate N(5) cavity of the [tptz-tptz](2-) ligand.
