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.

金属离子诱导的自组装簇的原位配体氧化：从双（5-（2-吡啶-2-基）-1,2,4-三唑-3-基）甲烷转化为酒精或酮
金属硝酸盐与配体双（5-（吡啶-2-基）-1,2,4-三唑-3-基）甲烷（H 2 L 1）的水热反应产生了三个簇化合物{Cr 2 }，{Zn 12 }和{Fe 8 }。值得注意的是，H 2 L 1的亚甲基在金属环{Zn 12 }中被原位氧化为羟甲基化（L 2 -O）3−或在螺杆中被氧化为刚性羰基化（L 3 = O）2−。输入{Fe 8 }。在比较实验结果的光，NO 3 -推测其在配体氧化中起催化作用。金属离子可被视为自组装过程中产生簇的“诱导”工具。
