Abstract

Exploration of the reactivity of the versatile polyoxometalate precursor [As₂W₁₉O₆₇(H₂O)]^14- with yttrium salts and organic proligands derived from 2-picolinic acid: 2,5-pyridinedicarboxylic acid (pdcH₂) and 5-(methoxycarbonyl)-2- pyridinecarboxylic acid (mcpcH), has afforded the three new hybrid complexes [Y{AsW₈O₃₀}₂(AsO)₂{WO ₂(pdc)}₂]^13- (1) and [{Y(H₂O) ₃}₂{As₂W₁₉O₆₈}{WO ₂(L)}₂]^8- (L^- = pdcH^- (2) or mcpc^- (3)). The structurally-related and organic ligand free species [{Y(H₂O)₃}₄{Y(H₂O) ₆}₂{As₂W₁₉O₆₈} ₂{WO₃(H₂O)}₄(AsO)₂] ^20- (4) was also obtained. Structural characterization of the mixed salts of the four complexes, K₈H₅[1]·9H ₂O, K_2.5H_5.5[2]·37H₂O, K _2.5H_5.5[3]·34H₂O and K ₆Na₂H₄[4]·30H₂O, has revealed that five membered N,O-chelated {WO₂(L)} units play a key structural role in complexes 1-3. With no picolinate-based ligand present in 4, additional arsenite fragments bind to the analogous tungsten coordination sites.
