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 C2h point-group symmetry. Polyanions
