Abstract	Pentan-2,4-dione reacts with phenylisothiocyanate to give 3-(N-phenylthiocarbamyl)pentan-2,4-dione (HPTPD) containing N, O and S donor atoms. HPTPD has been characterized by elemental analysis, i.r., $^{1}$H-n.m.r. and electronic spectral studies and its structure is confirmed by molecular modeling using a molecular mechanics program. Co$^{II}$, Ni$^{II}$, Cu$^{II}$, Zn$^{II}$ and Pd$^{II}$ complexes have been prepared and characterized by spectroscopic techniques. The Cu$^{II}$ complex has also been studied by e.s.r. spectroscopy. Upon formation of these complexes, except for Pd$^{II}$, loss of methine hydrogen occurs and HPTPD coordinates to the metal centers as a monoanionic bidentate ligand. Co$^{II}$ acetate forms two types of complexes according to the ratio of reactants. The first is brown–green having the formula [Co(PTPD)$_{2}$] and is characterized as square-planar and the other is blue with [Co(PTPD)(OAc)] formula and has a tetrahedral geometry; their thermal decompositions have been studied by t.g analysis. The other metal(II) complexes have square-planar structures based on magnetic and electronic spectral data.
