Abstract

The dihydride {(η⁵-C₅H₃)₂(SiMe₂) ₂}W₂(CO)₆(H)₂ (1), which contains a linked dicyclopentadienyl ligand, reacts with Ph₃C⁺ to give [{(η⁵-C₅H₃)₂(SiMe₂) ₂}W₂(CO)₆(μ-H)]⁺ (2H⁺).The W-H-W bond in 2H⁺ is cleaved upon reaction with I^- to give {(η⁵-C₅H₃)₂(SiMe₂) ₂}W₂(CO)₆-(H)(I) (3). Crystal structures of [{(η⁵-C₅H₃)₂(SiMe₂) ₂}W₂(CO)₆(μ-H)]⁺ (2H⁺ and its unprotonated analogue {(η⁵-C₅H₃)₂(SiMe₂) ₂}W₂(CO)₆ (2) are also reported and discussed.
