The new dinuclear Fe(III) complex, [Fe2(μ-L)2]·3(H2O)·0.38(O), [1, L (2) = (E)-2-(((5-(hydroxymethyl)-2-methyl-3-oxido-1κO-pyridin-4-yl)methylene)amino-1κN)-3-(3-(hydroxymethyl)-2-methyl-5-oxido-1κO-pyridin-1-ium-4-yl)-3-oxido-1:2κ2O-propanoato-2κO]* (*The second ligand has swapped indexes 1 and 2, denoting the individual Fe centers.), was synthesized by reaction of FeCl3·6H2O with potassium pyridoxylidenglycinate in ethanol-water solution Pentadentate pyridoxal Schiff base ligand was generated in situ by aldol condensation of potassium pyridoxylidenglycinate and pyridoxal. A C-C coupling was achieved at room temperature under metal template reaction. The complex was characterized by x-ray structural anal. at 100 K, elemental anal., spectral and magnetic measurements. The compound crystallizes in the monoclinic space group P21/n, with a 9.7445(15), b 19.489(3), c 20.862(6) Å, β 92.595(17)°. Structural anal. of the complex showed that each Fe(III) center has a distorted octahedral FeNO5 core, which is sixfold coordinated through iminic nitrogen atom, two phenoxido oxygen atoms, alkoxo oxygen atom and carboxylato oxygen atom from two Schiff-base ligands forming a rhombic arrangement of metal ions and oxygen atoms. In the structure, two Fe(III) atoms are connected with two alkoxo-bridging ligands providing covalent superexchange pathway by linkage Fe1-O-Fe2 with the Fe1···Fe2 distance of 3.195 Å. In the crystal lattice, the noncovalent interactions, hydrogen bonds, and π-π stacking interactions expand the mononuclear units to 3D supramol. network. The temperature dependent magnetic susceptibility data (6.5-300 K) indicate that the octahedral Fe(III) centers in this complex retain high-spin S = 5/2 (6A1g) in the whole temperature range. The effects of zero-field splitting (D = 7.67 cm-1) and an antiferromagnetic coupling (J = -14.66 cm-1) between the two alkoxo-oxygen bridged Fe(III) ions are discussed. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Recommanded Product: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride).
3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Recommanded Product: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride
