Abstract

A series o f zinc complexes of dimethyl(phthalimidomethyl)phosphine oxide (DPPO, L) have been synthesized: ZnX2L2, where X = Cl, Br, I or NO3. The complexes are characterized by elemental analysis, infrared and 1H NMR spectra and X-ray powder analysis. Infrared spectral data show that L is coordinated to zinc via the phosphoryl oxygen atom. The zinc halide complexes are found to be isostructural, while the pattern o f Zn(NO3)2L2 differs considerably from those o f halide complexes.
