Tungsten–Lead Triple Bonds: Syntheses, Structures, and Coordination Chemistry of the Plumbylidyne Complexes trans‐[X(PMe₃)₄WPb(2,6‐Trip₂C₆H₃)]

Plumb line: A series of compounds trans-[L(PMe3)4WPb(2,6-Trip2C6H3)]n+ (n=0: L=Br, I; n=1: L=PhCN, PMe3; Trip=2,4,6-iPr3C6H2; see structure of L=PMe3 derivative) containing WPb triple bonds is reported. Quantum-chemical analyses of the WPb bond in the plumbylidyne complex [(PMe3)5WPb(2,6-Trip2C6H3)]+ confirm the electronic analogy with Fischer-type carbyne complexes.
