By employing 1,4-diazabicyclo[2.2.2]octane (DABCO) as pillared ligand, a new 3D nano-scale zinc phosphite [Zn3(C6H12N2)2(HPO3)3] has been solvothermally prepared.Its structure is constructed of neutral zinc phosphite layers, which are composed of ZnO3N tetrahedral, ZnO3N2 trigonal bipyramidal and HPO3 pseudo-tetrahedral.The inorganic layers pack in an ABAB sequence with the DABCO ligands as pillars, thus generating a 3D framework.It is worth noting that the title compound exhibits 1D hexagonal 12-MR channels with extra-large pore (diameter about 1.0 nm × 1.0 nm).Topological analysis shows that the title compound is an unprecedented 3, 4, 5-connected network.
