eng	Trapping of the N,C,N-chelated organobismuth(I) compound, [2,6-(Me2NCH2)(2)C6H3] Bi, by its coordination toward selected transition metal fragments	The in situ reduction of the N,C,N-chelated bismuth(III) chloride (ArBiCl2) (where Ar = 2,6-(Me2NCH2)(2)C6H3) with 2 equivalents of K[B(s-Bu)(3)H] produced an unstable bismuth(I) compound ArBi (1) that was trapped by its coordination toward suitable transition metal fragments. Using this strategy a set of complexes with Group 6 metal carbonyls was obtained, i.e. [ArBiM(CO)(5)] (1-M; where M = Cr, Mo, W). The treatment of 1 with [Fe-2(CO)(9)] provided the expected complex [ArBiFe(CO)(4)] (1-Fe) along with [ArBi(Fe(CO)(4))(2)] (1-Fe-2) as a minor by-product. By contrast, the reaction of 1 with the dinuclear complex [Co-2(CO)(8)] furnished ionic complex [(ArBi)(2)Co(CO)(3)][Co(CO)(4)] (1-Co). All compounds were characterized using H-1 and C-13{H-1} NMR, IR and Raman spectroscopy. Molecular structures of 1-Cr, 1-Fe, 1- Fe2 and 1-Co were determined by the help of single-crystal X-ray diffraction analysis.
