V. Torocheshnikov et al., MN-55, C-13 COUPLING-CONSTANTS OF SOME SIGMA-ORGANOMANGANESE AND PI-ORGANOMANGANESE COMPLEXES, Magnetic resonance in chemistry, 32(6), 1994, pp. 348-352
Mn-55, C-13 coupling constants of sigma- and pi-organomanganese pentac
arbonyl, tetracarbonylphosphine and tricarbonyl complexes were determi
ned by lineshape analysis of the (CO)-C-13 and C-13(R) signals (R = al
kyl, acyl or aryl) using the iterative lineshape fitting program QUADR
. The (1)J(Mn-55,C-13) data are in the range 29-47 Hz for Mn-CO bonds
and 2-28 Hz for Mn-R bonds. The Mn-55 chemical shifts and linewidths a
re also reported.
