Abstract:
A composition represented by the chemical formula:(Cat).sub.m [M.sub.a V.sub.18 O.sub.42 XL.sub.3z ].sup.n-.multidot.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 VO.sub.4, SO.sub.4, Cl, Br, I, H.sub.2 O, HCOO and NO.sub.2 ;d) E is at least one species selected from the group consisting of H.sub.2 O, N.sub.2 H.sub.4 and organic solvents;e) L is at least one species selected from the group consisting of H.sub.2 O, O, NO, N.sub.2, acetyl acetone, pyridine, 2,2'-bipyridine, (H.sub.2 N(CH.sub.2).sub.d NH.sub.2) (d=2 or 3), RNH.sub.2 and R.sub.2 NH;where if L=monodentate, then z=4 andwhere if L=bidentate, then z=2 or 4; anda=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 andb=the number of solvent/neutral molecule(s)--E, in the lattice and is in the range of about 12 to about 30.
