Abstract
The η 3-allylundecacarbonylosmium tetrafluoroborate has been synthesized in high yield by treatment of Os 3(CO) 11MeCN with allyl alcohol and subsequent protonation. It has been studied by single-crystal X-ray diffraction. The compound crystallizes in the orthorhombic space group Pna2 1 (no. 33) with a 17.933(2), b 11.440(2), c 11.797(2)Å and D c 2.76 g cm −3 for Z = 4. A final R value of 0.046 ( R w = 0.083) based on 2067 reflections was obtained. The presence of the positively charged allyl ligand in the triosmium cluster lengthens the Os1Os2 and Os2Os3 bonds (0.057Å) and 0.074 Å, respectively) relative to the OsOs bonds in Os 3(CO) 12.
