Summary

The synthesis and characterisation of a number of new coordination compounds of PtII and PdII with the nitrogen donor ligand pyrazole (PzH) is described. These compounds arecis-Pt(PzH)2X2,tans-Pt(PzH)2X2, Pt(PzH)4X2 · n H2O (n = 0 or 1), Pd(PzH)4X2 and Pt(PzH)4PtCl4 where X = Cl, Br and I.cis-Pd(PzH)2X2 compounds could not be obtained;trans-Pd(PzH)2X2 compounds seem to exist in more than one crystal form.

The new compounds were characterised by chemical analyses, x-ray powder diffraction, i.r. and far-i.r. and by1H n.m.r. spectroscopy. The metal(II) ions are in all cases coordinated in a square planar geometry.
