Bismuth complexes containing Mn(CO)5 and Re(CO)5 fragments. Synthetic studies and structural characterisation by solid- and solution-state extended X-ray absorption fine structure spectroscopy

Abstract

The reaction between BiCl3 and 3 equivalents of Na[Re(CO)5] affords the complex [Bi{Re(CO)5}3]2, which is compared with the known [Bi{Mn(CO)5}3]1. The dimetal complexes [BiCl{M(CO)5}2](M = Mn, 3 or Re, 4) were prepared from reactions between BiCl3 and 2 equivalents of the corresponding metal carbonylate anion. The reaction between compound 1 or 2 and 0.5 equivalent of BiCl3 affords 3 and 4 respectively whilst the reaction between either 3 and 1 equivalent of BiCl3 or between BiCl3 and 1 equivalent of Na[Mn(CO)5] affords a compound formulated as [BiCl2{Mn(CO)5}]5. The syntheses of the bromide and iodide complexes [Bix{Mn(CO)5}2](X = Br, 6 or I, 7) are also described. In addition, solution infrared studies are reported on the time- and concentration-dependent decomposition of 3 in tetrahydrofuran (thf) together with details of a number of reactivity studies involing 3. Analysis of Bi-LIII edge and Mn-K edge extended X-ray absorption fine structure spectra for compounds 3 and 4 in solid and solution phases show evidence for oligo- or polymerisation through Bi ⋯ Cl interactions in the solids. In a thf solution of 3 these interactions are disrupted, and the monomeric species formed shows co-ordination of solvent to bismuth.
