A series of phosphine complexes of palladium (II) ligated with 1-substituted phenyl tetrazoline-5-thione have been prepared and identification of complexes are established on the basis of elemental analysis, magnetic susceptibility, conductivity, IR, UV-vis and 1 H NMR spectral data. The phenyl ring was substituted to correlate the electronic effect of such substituents on the magnitude of the anti-fungal activity against Aspergillus favus species.Key words: Palladium (II), Thioamides, antifungal activity, structure and Bonding such substituents on the magnitude of the bioactivities.

“…The manganese(II), cobalt(II), nickel(iI) and copper(II) complexes of doublydeprotonated N-methyl-2-thiooxamic acid are insoluble in all organic solvents; this insolubility provides strong evidence for their polymeric structure. Complex The detailed thermal study of the prepared complexes (using t.g./d.t.g., d.t.a, and d.s.c, techniques) will be described in a subsequent paper (33).…”

Synthetic procedures are described that allow access to the new monomeric complexes [-M(HA)z(H20)2 ].2H20 (M = Mn or Co), [M(HA)z(H20)2] (M = Fe, Ni or Zn) and [Cu(HA)2], and to the polymeric compounds [MA(HzO)] n (M = Mn, Co, Ni or Zn) and [CuA]~, where HzA = N-methyl-2-thiooxamic acid.The X-ray crystal structure of [Mn(HA)z(H20)2]-2H20 reveals a trans, cis, cis octahedral geometry around the metal ion. The singlydeprotonated ligand behaves as a bidentate chelate with ligated atoms being the neutral thioamide sulfur and one of the carboxylate oxygens. The complexes were characterized by elemental analyses, conductivity measurements, X-ray powder patterns, magnetic susceptibilities and spectroscopic (e.s.r., ligand field, i.r., far-i.r., Raman) studies. The vibrational analysis of the complexes is presented using OH/OD, NH/ND, CHg/CD 3 and metal isotopic substitutions. All data are discussed in terms of the nature of bonding in conjunction with known or assigned structures. The dianion A 2 acts as a bis-bidentate O,N/O,S bridging ligand yielding highly symmetrical squares planar (Cu H) and octahedral (Mn H, Co II, Ni II and Zn n) polymeric compounds.
