A rare 3D porous inorganic-organic polyoxoniobate framework based on the cubic polyoxoniobate-cupric-complex cage [Cu(en)2]@[Cu2(en)2(trz)2]6(Nb68O188) (1a), has been successfully synthesized by a hydrothermal method. The cubic cages 1a are connected with 4-(tetrazol-5-yl)pyridine to form a 1D pillar-like chain structure, and every 1D pillar-like chain is further linked with four adjacent pillar-like chains by the [Cu(en)2]2+ complex to form a 3D porous inorganic-organic polyoxoniobate framework with 4-connected CdSO4-type topology.
