The crystal structure of the olefin complex di-1,5-cyclooctadienesilver tetrafluoroborate

The structure of di-1,5-cyclooctadienesilver tetrafluoroborate was determined from single crystal X-ray diffraction data. The silver atom is four coordinated to the olefinic ends of the two cyclooctadiene molecules in a modified tetrahedral coordination described as "cubical". Bond lengths and other structural parameters are discussed and compared with the corresponding data found for other d10 and d8 olefin-metal complexes.
