Abstract
A range of complexes based on the high-nuclearity {W<small><sub>36</sub></small>} isopolyoxotungstate cluster, [H<small><sub>12</sub></small>W<small><sub>36</sub></small>O<small><sub>120</sub></small>]<small><sup>12–</sup></small>, with a triangular topology has been isolated by using the organic cation, protonated triethanolamine. In analogy to an 18-crown-6 crown ether with six oxygen donors on a ring, the cluster can form alkali and alkaline earth metal complexes {MCW<small><sub>36</sub></small>} (M = K<small><sup>+</sup></small>, Rb<small><sup>+</sup></small>, Cs<small><sup>+</sup></small>, NH<small><sub>4</sub></small><small><sup>+</sup></small>, Sr<small><sup>2+</sup></small> and Ba<small><sup>2+</sup></small>, <strong>1–6</strong>, respectively). Compounds <strong>1–6</strong> were characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy. Comparisons between the structures of <strong>1–6</strong> and 18-crown-6 as well as the symmetry directing influence of the organo-cations in the isolation of the overall cluster architecture are discussed.
