Notizen: Molekülstruktur von Re3Cl6(Acac)3 im Feststoff / Molecular Structure of Re3Cl6(Acac)3 in the Solid State

Dark red single crystals of Re3Cl6(Acac)3 are obtained from a solution of “ReCl3·2H2O” in acetylacetone by slow evaporation. The unit cell (monoclinic, P21/c, a = 1687.3(9), b = 963.4(5), c = 1664.3(9) pm, β = 108.97(4)°) contains four molecules of Re3Cl6(Acac)3. Each of the bidentate Acac(—) ligands substitutes one of the in-plane terminal and one of the out-of-plane terminal ligands with respect to the Re3 triangle.
