Abstract

The complex [SnMe₂L]Cl₂ [L = 6,6″-bis(α-methylhydrazino)-4′-phenyl-2,2′:6′, 2″-terpyridine] is involved in the dimethyltin(IV) mediated transient template condensation of L with glyoxal; the complex has been structurally characterised, and shown to possess a pentagonal-bipyramidal geometry about the metal. The transient template effect is seen to originate in a reduction in the hole size of the N₅ donor set on passing from the open-chain ligand to the macrocycle.
