✦ Synopsis

2dione dioximate ion and X = OH, 0CH3, 0C2H5, O-i-C&l, or 0-nCJi9) have been synthesized by adopting an in situ procedure using iron(D) chloride, pentane_2,4dione dioxime or I,tdiphenylethane-1,2dione dioxime and boric acid. The hydroxy or alkoxy groups have been derived from the solvent molecules. The compounds are all diamagnetic, well crystalline, intensely coloured (usually red or orange) and are obtained in satisfactory yields. The preparations have also been achieved in some cases by alcohol exchange trans-esterification reactions. Infrared and electronic spectra show that they are isostructural and have been presumed to possess structures between octahedral and trigonal prismatic.
