The self-assembly of nickel(II) nitrate hexahydrate and a rigid tetraphosphonic acid (H 8 L) under hydrothermal conditions has resulted in the formation of a Ni II phosphonate ( 1 ). In its structure, each phosphonyl group is protonated, along with the coordinated water molecules in the metal centers, endowing 1 with rich Brønsted acidic sites. The cycloaddition reaction of CO 2 and epoxides was carried out under ambient conditions to investigate the catalytic activity of 1, and the results show its excellent performance in the catalysis. Moreover, compound 1 can be easily separated and reused without significant reduction in the catalytic ability. The heterogeneous nature along with good catalytic performance entitles 1 as an excellent catalyst for CO 2 transformation.
