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.
