Abstract/Summary

A monoclinic variety with C2/c space group of the title complex [(VO)-O-V(L)(OCH3)](2), incorporating the doubly deprotonated benzoyl hydrazone of 2-hydroxy-5-methylacetophenone (H2L) was synthesized from the decomposition of [(VO)-O-IV(L)(bipy)] (where bipy representing the 2,2'-bipyridine) in methanol which has been reported very recently from our laboratory In this paper we report another monoclinic variety of this complex with P2(1)/n space group that showed some differences in bonding patterns in the solid state (but in solution they are almost identical) prepared by different synthetic method viz, from the equimolar reaction of [(VO)-O-IV(acac)(2)], H2L and imidazole in CH3OH.
