Claim:
Polyoxometalate (POM) represented by the formula (A n ) m+ [M 13 X 8 R q O y ] m− or solvates thereof, wherein A represents a cation, n is the number of the cations, m is the charge of the polyanion, M represents a transition metal selected from Pd, Pt, Au, Rh, Ir and mixtures thereof, X represents a heteroatom selected from As, Sb, Bi, P, Si, Ge, B, Al, Ga, S, Se, Te and mixtures thereof, R is a group covalently bound to X, provided X is P, As, Si or Ge, and is independently selected from the group consisting of H, alkyl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl, heterocyclyl, arylalkyl, arylalkenyl, cycloalkylalkyl, heterocyclylalkyl and heteroarylalkyl, wherein each of said alkyl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl and heterocyclyl can be unsubstituted or substituted with one or more groups which can be the same or different, each group being independently selected from the group consisting of halogen, alkyl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl, heterocyclyl, arylalkyl, arylalkenyl, cycloalkylalkyl, heterocyclylalkyl, heteroarylalkyl, —CF 3 , —OCF 3 , —CN, —OR 2 , —NR 2 R 3 , —C(O 2 )R 2 , —C(O)R 2 , —C(O)NR 2 R 3 , —SO 3 H, —SR 2 , —S(O 2 )R 2 , —S(O 2 )NR 2 R 3 , —N(R 2 )S(O 2 )R 3 , —N(R 2 )C(O)R 3 , —N(R 2 )C(O)NR 2 R 3 , —NO 2 and X-containing moieties through which a polyoxometalate molecule can be linked to one ore more other polyoxometalate molecules, each of R 2 and R 3 being independently selected from the group consisting of H, alkyl, aryl and cycloalkyl, q is the number of R ranging from 0 to 8 and y is the number of oxygen atoms ranging from 32 to 40.
