Technetium dimers Tc2(O2CCH3)4X2 (X = Cl, Br) were synthesized and studied by X-ray Absorption Fine Structure spectroscopy (XAFS). EXAFS analysis gave for Tc2(O2CCH3)4Cl2: d Tc-Tc = 2.18(1) Å, d Tc-Cl = 2.43(1) Å and for Tc2(O2CCH3)4Br2: d Tc-Tc = 2.19(1) Å, d Tc-Br = 2.63(1) Å. The Tc Tc separations are in agreement with Raman studies while the Tc-X distances are somewhat larger. Comparison with other Tc(III) quadruply bonded dimers indicates that the carboxylate compounds exhibit larger Tc-Tc separations. The effect of the terminal ligand (nature and position) on the Tc-Tc separation is discussed. |
