The self‐assembly of 4,4′‐dipyridylditelluride/diselenide and M(OTf) 2 {M = cis ‐[Pt(PEt 3 ) 2 ] 2+ or cis ‐[Pd(dppe)] 2+ ; dppe = 1,2‐bis(diphenylphosphino)ethane} yields [M(µ 2 ‐4,4′‐py 2 E 2 )] n (OTf) 2 n (E = Se, Te). The major and minor products, indistinguishable by simple proton NMR and phosphorus NMR spectroscopy, can be detected by heteronuclear ( 77 Se, 125 Te, and 195 Pt) NMR spectroscopy. The respective dimeric and trimeric structures are assigned by ESI and MALDI‐TOF mass spectrometry, and for the first time, their equilibria have been established. The rhomboid shape of the dimeric complex containing the Pt–N bond is confirmed by its X‐ray diffraction structure. The formation of the cluster‐type minor product [Pd 3 (µ‐E) 2 (dppe) 3 ](OTf) 2 has also been identified in the reactions of the Pd complexes.
