Synthesis and characterization of triosmium clusters containing a nitrite ligand; crystal and molecular structures of [N(PPh3)2][Os3(CO)10(μ-η 2-NO2)] and [Os3(μ-H)(CO)10(μ-η2-NO2)]

The cluster [Os₃(CO)₁₀(NCMe)₂] reacted with [N(PPh₃)₂]NO₂ in CH₂Cl₂ to give a novel red-orange complex [N(PPh₃)₂][Os₃(CO)₁₀(μ-η ²-NO₂)] in moderate yield, which underwent protonation with HBF₄·Et₂O in CH₂Cl₂ to give the neutral complex [Os₃(μ-H)(CO)₁₀(μ-η²-NO₂)] in high yield; X-ray crystal-structure analyses have shown that both clusters contain a μ-η²-bridging nitrite ligand.
