Abstract
Mixed-metal oxide-based solids composed of a linked array of a plurality of vanadium oxide building blocks wherein a vanadium and oxygen shell cluster encapsulate a central X unit, where X is at least one species selected from the group consisting of VO4, SO4, Cl, Br, I, H2O, HCOO and NO2 and associated methods of synthesis are provided.

A composition represented by the chemical formula:
- (Cat)m[MaV18O42XL3z]n−·bE,
- where:
- a) Cat is at least one cationic species;
- b) M is at least one species of metallic element;
- c) X is at least one species selected from the group consisting of VO4, SO4, Cl, Br, I, H2O, HCOO and NO2;
- d) E is at least one species selected from the group consisting of H2O, N2H4 and organic solvents;
- e) L is at least one species selected from the group consisting of H2O, O, NO, N2, acetyl acetone, pyridine, 2,2′-bipyridine, (H2N(CH2)dNH2) (d=2 or 3), RNH2and R2NH;
- where if L=monodentate, then z=4 and
- where if L=bidentate, then z=2 or 4;
- and
- a=2 or 3;
- m=the number of cations and is in the range of about 0 to about 12;
- n=the units of negative charge and is in the range of about 2 to about 6, except where m=0 in which case n=0 and
- b=the number of solvent/neutral molecule(s)—E, in the lattice and is in the range of about 12 to about 30.
