Different solvothermal reactions of ZnC2O4 with oxalic acid (H2ox) and 1, 2, 4-triazole (Htrz) successfully gave a new quaternary (NJTU-Bai83, NJTU-Bai=Nanjing Tech University Bai's group) and a new quinary (NJTU- Bai84) anionic metal-organic frameworks (MOFs), where NJTU-Bai83=(Me2NH2)2[Zn3(trz)2(ox)3]·2H2O and NJTU-Bai84=(Me2NH2)[Zn3(trz)3(ox)2]·H2O, respectively. With the [Zn2(ox)4(trz)2] secondary building unit (SBU) in NJTU- Bai83 replaced by the [Zn3(ox)2(trz)6] and planar [Zn(ox)2(trz)2] ones in NJTU-Bai84, 2D supramolecular building layers (SBLs) are changed from the A-layer and B-layer to another A-layer, while pillars are transformed from the tetrahedral [Zn(ox)2(trz)2] SBU to the irregular tetrahedral [Zn(ox)2(trz)2] and planar [Zn(ox)2(trz)2] SBUs. Thus, cdq-topological quaternary NJTU-Bai83 is tuned to (4, 4, 8)-c new topological quinary NJTU-Bai84. Two MOFs were well characterized by powder X-ray diffraction, thermogravimetric analysis, elemental analysis, etc.
