Solid-state 111Cd NMR studies on cadmium(II)-2,x-pyridinedicarboxylates. Crystal structure of 2,4-pyridinedicarboxylato triaqua cadmium(II) hemihydrate: [Cd(II)(2,4-pydc)(H2O)3] • 1/2H2O
The synthesis and characterisation by solid-state 111Cd NMR of Cd(2,3-), Cd(2,4-), Cd(2,5-) and Cd(2,6-pyridinedicarboxylato) • xH 2O is reported. Results indicate that the 111Cd NMR signal is very sensitive to the relative position of both carboxylates. Similar shifts (at 54.0 and 55.4 ppm) are fou...

Results indicate that the 111Cd NMR signal is very sensitive to the relative position of both carboxylates. Similar shifts (at 54.0 and 55.4 ppm) are found for the 2,4- and the 2,6-isomers where the carboxylates groups are meta to each other. For the 2,3- and 2, 5-derivatives (carboxylates in ortho and para positions), the signals are detected at 119.6 and 84.2 ppm. The crystal and molecular structure of the seven-coordinated cadmium complex, [Cd(2,4-pyridinedicarboxylato)(H 2O)3] • 1/2H2O is also reported. This data allows a correlation between Cd-O and Cd-N coordination and geometry with 111Cd chemical shifts. Additional coupling between 111Cd and 14N in 2,3- (also found in 2,4-pydc) suggests only one N is coordinated to Cd. The anisotropy magnitude, Δσ, and the asymmetry parameter, η, are also analysed. © 2005 Elsevier Ltd. All rights reserved.
