A dinuclear and a tetranuclear complex of lead(II) with the pincer-type ligand 4′-(4-chlorophenyl)-2,2′:6′,2″-terpyridine (Cl-Ph-tpy), [Pb 2 (Cl-Ph-tpy) 2 ( μ -I) 2 I 2 ] ( 1 ) and [Pb 4 (Cl-Ph-tpy) 4 ( μ -Br) 4 ( μ -OH 2 )Br 4 ]·2CH 3 OH ( 2 ), have been synthesized and characterized by elemental analysis, FT-IR and  1 H NMR spectroscopy, and by single-crystal X-ray diffraction. In the binuclear structure of  1 , the Pb atom has a hemidirected PbN 3 I 3  environment with a Pb( μ -I) 2 Pb central unit. In the tetranuclear structure of  2 , two crystallographically independent Pb(II) centres having hemidirected PbN 3 Br 3  and PbN 3 OBr 2  environments are connected to Pb( μ -Br)Pb( μ -Br) 2 ( μ -OH 2 )Pb( μ -Br)Pb chains. The supramolecular features in  1  and  2  are supported through weak but directional C–H···Cl, C–H···I and C–H···Br, C–H···O, O–H···Br, and O···Br interactions and aromatic π-π stacking.
