Hydrothermal reactions of metal nitrates and ligand bis(5-(pyridine-2-yl)-1,2,4-triazol-3-yl)methane (H2L1) gave three cluster compounds, {Cr2}, {Zn12} and {Fe8}. Notably, methylene group of H2L1 was in situ oxidized either to hydroxymethylated (L2-O)3− in the metallo-ring {Zn12} or to a rigid carbonylated (L3=O)2− in the screw-type {Fe8}. In light of comparative experimental results, NO3− was deduced to be of a catalytic role in the ligand oxidation. Metal ion could be regarded as an “induced” tool for clusters generation in self-assembly process. Metal-ion induced in situ hydroxymethylation or carbonylation of ligand bis(5-(pyridine-2-yl)-1,2,4-triazol-3-yl)methane (H2L1) was captured in hydrothermally synthesized metallo-ring {Zn12(L2-O)6} and screw-type {Fe8(L3=O)6}.
