Abstract EN
The new complexes [M2O5L2(H2O)2]⋅H2O (M=Mo,1;M=W,2), [RuL2(H2O)2]⋅H2O (3), [ML3]⋅xH2O (M=Rh,x=2,4;M=Ir,x=1,5), [RhL2(PPh3)2](ClO4)⋅2H2O (6), [PdL2]⋅2H2O (7), [PdL(phen)]Cl⋅H2O (8), [ReOL2(PPh3)]Cl (9) and [UO2L2] (10) are reported, where LH is 4,6-diamino-1-hydro-5-hydroxy-pyrimidine-2-thione.
The complexes were characterized by elemental analyses, physical techniques (molar conductivity, room-temperature magnetic susceptibility), and spectroscopic (IR, Raman, UV/VIS/ligand field, NMR, mass) methods.
The ligand L− is in its thione form and behaves as a bidentate chelate with the deprotonated (hydroxyl) oxygen and the nitrogen of one amino group as donor atoms.
Oxobridged dinuclear (1, 2) and various mononuclear (3–10) structures are assigned for the complexes in the solid state.
The metal ion coordination geometries are octahedral (1–6, 9, 10) or square planar (7, 8).
The free ligand LH and complexes 1, 4, 7, and 8 were assayed in vitro for antimicrobial activity against two bacterial and two fungal cultures.
