Chemistry and structure of an inorganic analogue of a carboxylic acid: Hydroxobis(8-quinolinato)oxovanadium(V)

Basic hydrolysis, under mild conditions, of (μ-oxo)bis[bis(8-quinolinato)oxovanadium(V)], [(Q2VO)2O](Q = 8-quinolinato anion), obtained by a one-step synthesis, gave a dioxovanadium(V) complex, [Q2VO2]-, containing the VO2- unit. The structure of this anionic species was determined by an X-ray analysis carried out on the corresponding salts {[Q2VO2Na(H2O)2] 2(μ-DMF)} (VI) and {[Q2VO2](n-Bu4N)·H2O} (VII). The VQ2 unit has similar structural characteristics in both complexes, with the two N donor atoms trans to the oxo groups, which have a cis configuration. The V-N bonds, as a consequence, have the longest distances so far encountered (V-Nav = 2.33 A?). Complex VI is a dimer, where two VO2 units are bridged by two Na+ ions sharing the oxygen of a DMF molecule. In complex VII the oxygen is only weakly bonded to a H2O molecule, via hydrogen bonding. In both complexes the structural data concerning the VO2 units are very close, with a V-O-V angle varying from 105.7 (2)° in complex VI to 106.1 (5)° in complex VII, while the V-O bond distances have a double-bond character [1.647 (4) and 1.628 (2) A? in complex VI; 1.62 (1) A? in complex VII]. The O?O bite values are 2.610 (4) A? (complex VI) and 2.58 (1) A? (complex VII). These results invite comparison of the VO2- unit with the carboxylato group RCO2-. The relationship between other vanadium(V) derivatives and organic functional groups related to a carboxylic acid is reported. The inorganic analogue of a carboxylic acid itself is obtained on acidifying an aqueous solution of [Q2VO2]-. [Q2V(O)(OH)], which is a very well-known analytical reagent for organic compounds, was found to be a weak acid with a pKA of 6.3.

The final R factor was 4.7% for 2867 observed data. Crystallographic details for {[Q2VO2](n-Bu4N)·H2O]}: space group I42d (tetragonal); a = b = 19.04 (3), c = 19.486 (3) A?; V = 7064.1 A?3; Z = 8. The final R factor was 5.9% for 568 observed data.
