•Triazenide complexes are versatile tectons.•Pb-η6–arene π interactions are obtained from complexing reactions.•Reactions with Pb(II) and the ligand triazene give a supramolecular-assembling structure.
Pb(SCN)2 reacts with metallic sodium (Na0) 1-phenyl-3-(4-nitrophenyl) triazene 1-oxide in tetrahydrofuran, leading to the formation of orange-colored crystals of the [PbII {O2N(C6H4)NNN(O)Ph}2] complex, which is the first lead (PbII) complex with reciprocal metal–η6arene π-interactions. The crystal structure belongs to the monoclinic space group P21/n and the lattice of [PbII {O2N(C6H4)NNN(O)Ph}2] can be viewed as a unidimensional supramolecular assembling of [PbII {O2N(C6H4)NNN(O)Ph}2] units linked through intermolecular metal–arene π-interactions.
