Abstract

Treatment of MnBr(CO)5 with one equivalent of the bidentate ligand, 2-{RECH(2-n)(SiMe3)n} C5H4N (E=S, R=Me, Ph, n =0; E=Se, R=Me, n=0, 1, 2) affords the complexes [MnBr(CO)3L] as orange powders. The effect of stepwise substitution at the α-carbon of the ligand by a trimethylsilyl group was investigated using 77Se{1H}- and 55Mn-NMR, and IR spectroscopies. In the case of the pyridyl-selenoether-containing complexes, each additional Me3Si- group increases the σ-donating properties of the ligand, in turn reflected in increased Mn→CO backbonding. The solid-state structure of the parent [MnBr(CO)3{2-(PhSCH2)C5H4N}] showed the molecule to have distorted fac-octahedral geometry. All other compounds were assigned the same stereochemistry based on C≡O stretching frequency comparisons. © 2003 Elsevier Science B.V. All rights reserved.
