type of 3D “strongly” self-catenated metal–organic
framework (SDU-9) has been constructed from [Cu2(COO)4] paddlewheel secondary building units and a tripodal
carboxylate linker. SDU-9 ([Cu6(H2O)6L4]·24H2O,
where [H3L = 4,4′,4″-(hydroxysilanetriyl)tris(triphenyl-4-carboxylic
acid), represents a rare example of a highly symmetrical coordination
network and extremely tight self-catenation. To the best of our knowledge, SDU-9 has the highest topological density among all known
3,4-coordinated nets.
