• Hybrid framework
• Polymeric iodoplumbate
• Optical adsorption

A 3-D supramolecular hybrid {[La(EPC)(3)(H2O)(3)](2)(Pb6I18)}(n) (EPC+ = N-ethyl-pyridium-4-carboxylate) (1) has been structurally determined, which assume significance for its incorporating lanthanide metal-carboxylic coordination polycation into polymeric iodoplumbate to get heterometallics. 1 consists of 1-D (Pb6I18)(n)(6n-) zigzag-like anion chains with lanthanide metalcarboxylic [La(EPC)(3)(H2O)(3)](n)(3n+) polycations, which arrange in a criss-cross configuration. C-H center dot center dot center dot I and C-H center dot center dot center dot O hydrogen bonds among inorganic anions and polycations contribute to the formation of a 3-D supramolecular framework. Moreover, the framework displays an absorption edge at 2.46 eV which is comparable to PbI2's absorption edge.
