The reactions of (η5 − C5H5)2MCl2 (M = Ti, Zr, or Hf) with mercaptoazoles (LH2), namely, bis(mercaptotriazoles), bis(mercap- tooxadiazoles),
and bis(mercaptothiadiazoles) in 2 : 1 molar ratio, respectively, have been studied in dry tetrahydrofuran in
the presence of n-butylamine and the binuclear complexes of the type [{(η − C5H5)2 M}2(L)] (M = Ti/Zr/Hf) are obtained. Tentative structural conclusions are drawn for the reaction
products based upon elemental analysis, electrical conductance, magnetic moment, and spectral
data (UV-Vis, IR, 1H NMR, and 13C NMR). FAB-mass spectra of few complexes of each series were also carried out to
confirm the binuclear structures. Studies were conducted to assess the growth-inhibiting
potential of the complexes synthesized, and the ligands against various fungal and bacterial strains
