Three bimetallic triangles were constructed via a step-wise assembly of tailored terpyridine building blocks. Oligomeric trimer 2 was obtained by reacting ligand 1 with Ru(II). Subsequent cyclization of trimer 2 with Zn(II), Cd(II), and Fe(II) resulted in the formation of bimetallic triangles 3, 4, and 5 in high yield, respectively. All triangles were characterized by NMR spectroscopy, ESI and travelling-wave ion mobility-mass spectrometry (MS), as well as gradient MS, which provided insight into their stabilities.

走向有用的金属单体的途径：通过特定位置的金属化逐步构建双金属三角形

通过分步组装量身定制的吡啶吡啶构建三个双金属三角形。通过使配体1与Ru（II）反应获得 低聚三聚体2。三聚体随后的环化2用Zn（II），镉（II）和Fe（II）导致的双金属三角形的形成3，4，和5分别以高收率。通过NMR光谱，ESI和行波离子迁移率质谱（MS）以及梯度MS对所有三角形进行了表征，从而洞悉了其稳定性。
