Abstract

Four heterobimetallic U(vi)/M(ii) (M = Mn, Co, Cd) carboxyphosphonates have been synthesized. M2[(UO2)6(PO 3CH2CO2)3O3(OH)(H 2O)2]·16H2O (M = Mn(ii), Co(ii), and Cd(ii)) adopt cubic three-dimensional network structures with large cavities approximately 16 in diameter that are filled with co-crystallized water molecules. [Cd3(UO2)6(PO3CH 2CO2)6(H2O)13] ·6H2O forms a rhombohedral channel structure with hydrated Cd(ii) within the channels. The cubic compound (Co) displays differential gas absorption with a surface area for CO2 uptake of 40 m2 g-1 at 273 K, and no uptake of N2 at 77 K.
