Nature of NMR Shifts in Paramagnetic Octahedral Ru(III) Complexes with Axial Pyridine-Based Ligands.

ABSTRACT: In recent decades, transition-metal coordination compounds have been extensively studied for their antitumor and antimetastatic activities. In this work, we synthesized a set of symmetric and asymmetric Ru(III) and Rh(III) coordination compounds of the general structure (Na⁺/K⁺/PPh₄⁺/LH⁺) [trans-M^IIIL(eq)_nL(ax)₂]^- (M = Ru^III or Rh^III; L(eq) = Cl, n = 4; L(eq) = ox, n = 2; L(ax) = 4-R-pyridine, R = CH₃, H, C₆H₅, COOH, CF₃, CN; L(ax) = DMSO-S) and systematically investigated their structure, stability, and NMR properties. ¹H and ¹³C NMR spectra measured at various temperatu
