T1 - Synthesis, structure and NMR studies of trinuclear Mo3S4 clusters coordinated with dithiophosphate and chiral carboxylate ligands LA - eng PY - 2016 SP - 7612 EP - 7619 T2 - New Journal of Chemistry SN - 1369-9261 VL - 40 IS - 9 PB - Royal Society of Chemistry AB - New chiral cluster complexes containing (S)-mandelate and (S)-phenyllactate ligands, [Mo3S4(dtp)3(μ-(S)-mandelate)(py)] (1) and [Mo3S4(dtp)3(μ-(S)-phenyllactate)(py)], were prepared from [Mo3S4(dtp)3(μ-dtp)(H2O)] (dtp = (EtO)2PS2) by ligand substitution. The crystal structures of 1 and 2 were determined by X-ray diffraction. Detailed variable-temperature 31P{1H} and 1H NMR studies of solutions of 1 and 2 in non-coordinating solvents (CDCl3, CD2Cl2) demonstrated three dynamic processes at the Mo-Py coordination site: diastereomer interconversion [(PS) to (MS)] which is inhibited at low temperatures; pyridine rotation around the Mo-py bond (180°-flip), and pyridine exchange in the presence of added pyridine. Activation parameters for all exchange processes have been estimated.
