Previously published one-bond Mn-55,C-13 coupling constants have been
recalculated using a revised lineshape fitting program, QUADR. The acc
uracy of the new data was confirmed by the simulation of quadrupole-br
oadened but resolved C-13 and F-19 spectra of the model complexes K-3/
Co(CN)(6)/ and Li/AsF6/. The Mn-55, C-13 coupling constants lie in the
range 128-189 Hz for Mn-CO bonds, 57-114 Hz for Mn-C(sp(2)) bonds and
35-79 Hz for Mn-C(sp(3)) bonds.
