Schiff-base condensation of an equimolar proportion of diacetyl-monoxime and 2-hydrazino pyridine in methanol gives rise to 2-hydroxyimino-3-(2-hydrazonopyridyl)-butane (HL). The ligand has been characterised by FT-IR, 1H NMR and UV–Vis spectra. Reaction of 1:1 stoichiometric proportion of HL with Na2[PdCl4] in methanol affords a mononuclear palladium(II) compound, [PdLCl]·H2O (1). The compound is characterised by C, H and N analyses, FT-IR, conductivity measurement, UV–Vis spectra, thermal analysis and magnetic susceptibility measurement. The X-ray crystal structure of the title compound (1) has been determined. The compound crystalises in the triclinic space group $$ P\overline1} $$ with a = 7.3033(3), b = 9.4139(4), c = 9.4445(5) Å, α = 79.789(3), β = 68.285(2), γ = 77.978(3)º, V = 586.42(5) Å3 and Z = 2. Pd(II) is in ‘N3Cl’ coordination chromophore. The geometry around Pd(II) is square-planar. The compound is essentially diamagnetic. A mononuclear complex of palladium(II) with 2-hydroxyimino-3-(2-hydrazonopyridyl)-butane has a square-planar coordinated geometry. The compound is essentially diamagnetic.
