A novel metal-organic framework, {[Zn2Cl4(C25H24N4O4)].4C3H7NO}n, was synthesized solvothermally by assembling the semi-rigid tetrahedral ligand tetrakis[(pyridin-4-yl)oxymethyl]methane (tpom) and Zn(NO3)3 in DMF. Crystal data: tetragonal, P4̅21c, a = 12.2905(14), c = 16.133(4) Å, Z = 2, 2149 observed reflections with I > 2σ(I), 136 refined parameters, R[F2 > 2σ(F2)] = 0.031, wR(F2) = 0.086. Each Zn(II) cation has a tetrahedral coordination environment (C 2 symmetry), which is formed by 2 chloride ligands and two pyridine N atoms from 2 tpom ligands. The tetrahedral tetradentate tpom linker has a quaternary C atom located on the crystallog. axis. This linker utilizes all the peripheral pyridine N atoms to connect 4 Zn(II) cations, thereby forming a wave-like 2-dimensional sheet along the c axis. The 2D layer can be topol. simplified as a typical uninodal 4-connected sql/Shubnikov net, which is represented by the Schlaefli symbol {44,62}. Adjacent layers are further packed into a 3D structure by C-H…Cl H-bonds.
