1,3,5-Trimethyl-1,3,5-triazacyclohexane (Metach) readily complexes uranium triiodide to form (Metach)UI. The complex is soluble in THF and arenes and can function as a source of UI to form organometallic U(III) complexes. When dissolved in pyridine (py), (Metach)UI forms (Metach)UI(py). A related complex with the larger 1,4,7-trimethyl-1,4,7-triazacyclononane (Metacn) ligand, namely (Metacn)UI(THF), was synthesized for comparison. Since X-ray quality crystals of (Metach)UI can be synthesized in high yield even with small-scale reactions, the system is ideal for extension to transuranium elements. Accordingly, the neptunium and plutonium complexes (Metach)NpI and (Metach)PuI were synthesized in an analogous manner from NpI(THF) and PuI(THF), respectively.
1,3,5-三甲基-1,3,5-三氮杂环庚烷（Metach）很容易与三碘化铀形成配合物（Metach）UI。该配合物可溶于四氢呋喃和芳烃中，并可作为 UI 的来源，形成有机金属 U(III)配合物。当溶解在吡啶（py）中时，（Metach）UI 形成（Metach）UI(py)。为了进行比较，还合成了一种具有更大 1,4,7-三甲基-1,4,7-三氮杂环壬烷（Metacn）配体的相关配合物，即（Metacn）UI(THF)。由于即使在小规模反应中也可以高产率合成（Metach）UI 的 X 射线质量晶体，因此该系统非常适合扩展到超铀元素。因此，分别从 NpI(THF)和 PuI(THF)合成了相应的镎和钚配合物（Metach）NpI 和（Metach）PuI。
