Iron(III), chromium(III) and cobalt(II) complexes with squarate: Synthesis, crystal structure and magnetic properties

“…However, the squaratecontaining di-l-hydroxodimetal(III) species are formed in this reaction with trivalent 3d metal ions due to the easy hydrolysis that these metal ions undergo in aqueous solution in the presence of squarate [10][11][12][13]. Our efforts to isolate some of these hydroxobridged species afforded the compounds of formula [Fe 2 (OH) 2 - (C 4 (3).…”

Octahedral Lattice Distortion-Driven Ferroelectricity and Canted Antiferromagnetism in Oxalate and Phenanthrolin Ligand-Based Chain Molecular Magnets [{Fe(Δ)Fe(Λ)}1–x{Cr(Δ)Cr(Λ)}x(ox)2(phen)2]n (x = 0, 0.1, and 0.5)

“…There has been an increasing attraction toward the synthesis and characterization of SCMs ,,− with new functionalities making such compounds multifunctional as well. , Recent incorporation of π-functional organic molecules in SCMs seems interesting because of the observation of spontaneous magnetization in such compounds, which is a rather rare phenomenon in the series of π-functional magnetic materials. − The π–π interaction may give rise to a short-range or a long-range magnetic ordering, and consequently, new materials with distinct magnetic properties may emerge . For example, the oxalate and phenanthroline-based π–π molecular magnet, [{Fe­(Δ)­Fe­(Λ)}­(ox) 2 (phen) 2 ] n exhibits spontaneous magnetization below ∼10 K as reported by Li et al , Further, spontaneous magnetization above room temperature has been observed in a coordination π–π framework of 1D polymeric Cu­(II) chains with 2,2′-bipyridine ligands .…”
