Aa. Holder et al., SYNTHESES, CHARACTERIZATION, INFRARED AND MO-95 NMR-SPECTROSCOPY OF SOME COORDINATED OXO-MOLYBDENUM(VI) COMPLEXES, Inorganica Chimica Acta, 260(2), 1997, pp. 225-228
Adducts with MoO42-tetrahedra coordinated to Cr(III) or Co(III) comple
xes have been synthesised and studied by IR and high resolution Mo-95
NMR spectroscopy. The Mo-95 chemical shifts of the adducts with cobalt
(III) lie in the range -33.2 to +49.4 ppm. This may be compared with a
n overall known chemical shift range in excess of 7000 ppm and implies
a similarity in the molybdenum environment in all cases. For adducts
with chelated cobalt(III) complexes several rather broad Mo-95 signals
are obtained with linewidths up to 260 Hz.
