The article conveys some information:
Two Mn/Ln clusters, [Mn2Ln2(O2CMe)6(pdmH)2L](NO3)·H2O (Ln = Dy (1), Gd (2)), were synthesized and exptl. studied by x-ray crystallog., PXRD, magneto- and electrochem., pdmH2 = 2,6-pyridine dimethanol; LH2 = (6-hydroxymethylpyridin-2-yl)-(6-hydroxymethylpyridin-2-ylmethoxy)methanol. By x-ray anal., the two complexes are isomorphous, both possessing one [MnIIMnIIILnIII2(μ3-O)2]6+ core with four metal atoms in one plane arranged in a butterfly conformation. This is the 1st time that mixed-valent manganese (MnII and MnIII) and LnIII heterometal tetranuclear complexes were isolated and characterized. Magnetic susceptibility measurements reveal that compounds 1 and 2 both display overall weak ferromagnetic exchanges between the metal ions within the clusters. The temperature dependencies of the out-of-phase (χM’) and in-phase (χM’) a.c. susceptibility signals exhibit no significant frequency-dependency for compounds 1 and 2, which suggests that the two complexes may not be SMMs. Electrochem. studies indicate that compounds 1 and 2 can both catalyze water oxidation at a potential of ∼1.70 V with an overpotential of ∼880 mV vs. Normal H electrode, which could be due to a cooperative catalytic effect between the manganese and lanthanide ions.

2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Computed Properties of C7H9NO2
