Investigation of the preparation and reactivity of metal-organic frameworks of cerium and pyridine-2,4,6-tricarboxylate.

The synthesis of three coordination polymers of cerium(III) and the ligand pyridine-2,4,6-tricarboxylate (PTC) is reported. Two of the materials crystallise under hydrothermal conditions at 180 °C, with [Ce(PTC)(HO)]·1.5HO, (1), being formed on extended periods of reaction time, 3 days or longer, and Ce(PTC)(HO), (2), crystallising after 1 day.
