Tetrakis(pyridine)tetrachloro(μ-chloro)(μ-hydrido)ditungsten(W-W) and its 4-ethylpyridine homologue. Compounds derived from a quadruply bonded dimer by ligand exchange and oxidative addition of hydrogen chloride

Reaction of W{sub 2}(mhp){sub 4} (mhp = anion of 6-methyl-2-hydroxypyridine) with (CH{sub 3}){sub 3}SiCl and pyridine in the presence of methanol provides the light brown compound W{sub 2}HCl{sub 5}(NC{sub 5}H{sub 5}){sub 4}. The 4-ethylpyridine adduct W{sub 2}HCl{sub 5}(NC{sub 5}H{sub 4}C{sub 2}H{s...
