Arsenic(III)-Capped 12-Tungsto-2-Arsenates(III) [M2(AsIIIW6O25)2(AsIIIOH)x]n (M = CrIII, FeIII, ScIII, InIII, TiIV, MnII) and Their Magnetic Properties

Abstract: Six arsenic­(III)-capped 12-tungsto-2-arsenates­(III) of the type [M2­(AsIII­W6­O25)2­(AsIII­OH) x ] n− (M = CrIII, 1; FeIII, 2; ScIII, 3; InIII, 4; TiIV, 5; MnII, 6) have been synthesized in aqueous medium by direct reaction of the elements using a one-pot strategy and structurally characterized by FT-IR spectroscopy, single-crystal XRD, and elemental analysis. Polyanions 1–6 are comprised of two octahedrally coordinated guest metal ions M sandwiched between two {AsW6} units, resulting in a structure with C 2… Show more

“…This is to be expected from the crystal structure given that since the distance between the Mn 3+ ions is quite large (3.235 Å). Additionally, the absence of any long‐range antiferromagnetic ordering is consistent with the small magnitudes of the exchange constants between the magnetic ions, as noted above [68–70] …”

“…Moreover, their open structure can function as appropriate chelating pockets for encapsulating lanthanide (Ln) ions. 5 Polynuclear Ln-POMs are a subject of great interest due to their potential applications in luminescence and their significance in molecular magnetism, particularly in single-molecule magnets (SMMs). 3 Most lanthanide-based single-molecule magnets (SMMs) in the literature use organometallic or organic ligands, 6 and the non-rigid nature of most of these ligands reduces the chances of achieving the targeted symmetry.…”
