Abstract
Due to the recent increase in understanding of vanadium's role in the biological world, it is desirous to synthesize many metallorganic complexes of vanadium. As vanadium is frequently found complexed to oxygen or nitrogen atoms in biological systems, several Schiff base complexes were synthesized and characterized. These complexes were of the form VO(IV)(sahbase) (baseH4 = 1,2-diaminoethane, 1,3- diaminopropane, and a-phenylenediamine). These complexes were then chlorinated with thionyl chloride or oxidized with nitrosonium hexafluorophosphate. In addition, because vanadium(IV) has a d 1 electronic configuration, this simplifies any of its magnetic interactions. Large amounts of the macro cyclic metallorganic complex [(VOhli!:: OAc)(L)t BF4- were desired to study the magnetic properties of two adjacent but not bonded vanadium atoms in a variable temperature magnetic susceptometer. The existing synthesis needed to be optimized such that large amounts of the pure compound could be synthesized easily.
