Two new solvates of the dinuclear salt {(η5-C5H5)(CO)2Fe}2(ji-DABCO)](BF4)2 (DABCO = 1,4-diazabicyclo[2.2.2]octane); 1 (D2O solvate) and 2 (acetone solvate), and the mononuclear salt [(η5-C5H5)(CO)2Fe(DABCO)]BF4,3, have been synthesized and structurally characterized. The D2O solvate, 1 forms crystals in the triclinic space group PIMAGEM AQUI, the acetone solvate forms crystals in the monoclinic P21/c space group, while the unsolvated mononuclear salt, 3, forms crystals in the orthorhombic P212121 space group.
