Synthesis and structure of [bis(pyrazol-1-yl)acetato]trioxorhenium(VII) and [bis(3,5-dimethylpyrazol-1-yl)acetato]trioxorhenium(VII) Review Article

The coordination of the ligands bis(pyrazol-1-yl)acetate (bpza) and bis(3,5-dimethylpyrazol-1-yl)acetate (bdmpza) to rhenium(VII) was investigated. The compounds [(bpza)ReO3] and [(bdmpza)ReO3] were synthesised by reaction of bpza and bdmpza with perrhenic acid with the loss of one water molecule. The new complex [(bdmpza)ReO3] was characterised by single-crystal X-ray analysis. It has a monomeric structure with a distorted octahedron for the [N,N,O]ReO3 central core.
