A new 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.
