“…It also indicates the presence of many low-lying excited states. The J values of Na-1 and Na-2 are comparable with those determined for several other Cr III dimers . For example, the J value of an alkoxo-bridged Cr III dimer has been reported at −3.67 cm –1…”

The dichromium(III)-containing heteropoly-16-tungstates [Cr(B-β-SiWO)] (1) and [Cr(B-β-GeWO)] (2) were prepared via a one-pot reaction of the composing elements in aqueous, basic medium. Polyanions 1 and 2 represent the first examples of Cr-containing heteropolytungstates comprising the octatungstate unit {XWO} (X = Si, Ge). Magnetic studies demonstrated that, in the solid state, the two polyanions exhibit a weak antiferromagnetic interaction between the two Cr centers with J = -3.5 ± 0.5 cm, with no long-range ordering down to 1.8 K. The ground-state spin of polyanions 1 and 2 was thus deduced to be 0, but the detection of a complex set of EPR signals implies that there are thermally accessible excited states containing unpaired spins resulting from the two S = / Cr ions. A comprehensive electrochemistry study on 1 and 2 in solution was performed, and biological tests showed that both polyanions display significant antidiabetic and anticancer activities.

“…The (2) -18.9 (3) dimensions [except those involving 0(43), which did not refine well] are very close to previously reported values (e.g. Robertson & Whimp, 1975;Cline, Scaringe, Hatfield & Hodgson, 1977…”
