ISOLATION OF PENTAMETHYLCYCLOPENTADIENYLCHROMIUM TRICARBONYL DIMER BY 2 METHODS - X-RAY CRYSTAL STRUCTURAL STUDY OF 2 POLYMORPHS Academic Article

abstract

• The [(C5Me5)Cr(CO)3]2 dimer has been prepared by two methods, (i) oxidation of the anion [(C5Me5)Cr(CO)3]- by ferric ions in an aqueous acidic medium, and (ii) carbonylation of [(C5Me5)Cr(CO)2]2 under high CO pressure at elevated temperatures. The complex crystallises in the monoclinic system in two polymorphic forms (I and II). Crystal structure data: I: space group P21/c, a = 8.376(4), b = 19.397(6), c = 8.805(5) , = 117.40(3), U = 1269.8 3, Z = 2, Dc = 1.419 g cm-3, and II: space group P21/n, a = 9.333(2), b = 8.998(1), c = 15.297(3) , = 95.86(2), U = 1277.9(1) 3, Z = 2, Dc = 1.37 g cm-3. 1990.
