• The reactions of 16 newly synthesized <I>N</I><SUP>1</SUP>-hydroxy-<I>N</I><SUP>1</SUP>,<I>N</I><SUP>2</SUP>-diarylbenzamidines with vanadium(V) in presence of various adduct-forming substances have been investigated photometrically in chloroform. The present study indicated the formation of 1:2:1 metal:reagent:acetic acid or phenol and 1:2:2 metal:reagent:thiocyanate complexes. On the basis of strong synergism, which is attributed to mixed-complex formation, simple, rapid, sensitive and selective methods for the spectrophotometric determination of microgram quantities of vanadium(V) have been developed. The influence of experimental variables on the procedures have been discussed.
