The reaction of α-H3[PW12O40] with Y(NO3)3 in the presence of DMF or DMSO leads to two complexes with the formulae {Y(DMSO)7}·PW12O40(1) and {[Y(DMF)7]2PW12O40}·PW12O40(2). The crystal structures indicate that complex 1 consists of discrete [YLn]3+ cations and α-Keggin heteropolyanions [PW12O40]3-, whereas, in complex 2, donor-acceptor interaction results in a cation-anion-cation triplet. In addition, the electrochemical behavior of the two complexes indicates the usual successive reduction processes of the W atoms in the anions.
