ABSTRACT:
A solid composition of matter comprising heteropolyoxo vanadium oxide compounds of the general formula: (R'.sub.4 N).sub.x H.sub.y (VO.sub.b).sub.a (RQO.sub.3).sub.-- nH.sub.2 O) wherein (VO.sub.b).sub.a (RQO.sub.3) is a molecular anion; R' is a substituted or unsubstituted monovalent organic group covalently bound to nitrogen to form a tetraorgano ammonium cation (R'.sub.4 N); R is a substituted or unsubstituted monovalent organic group covalently bound to Q to form an organophosphorus or organoarsenous group; R and R' are selected from the group consisting of C.sub.1 -C.sub.20 alkyl, aryl, hetero alkyl, hetero aryl or mixtures thereof; Q is a phosphorus or arsenic atom; a is about 1.0 to about 3.0; b is about 1.0 to about 2.0; (x+y) are determined by the vanadium oxidation state (m) where (x+y) equals (2ab+2)-ma and where (x+y) and x can not equal zero; and n is zero or a positive number.
