The intensely blue salts B+ [MoO(SAr)4]- (B+ = quaternary cation; Ar = phenyl, p-tolyl) have been isolated. Magnetic susceptibility, e.s.r., conductance and electronic spectral data indicate that the complexes are essentially mononuclear both in the solid state and in solution. The solution electronic spectra exhibit an intense maximum at 598 nm, which is tentatively assigned to a sulphur-to-molybdenum charge- transfer transition.

Complexes of Co(II) with two new Schiff bases TEAB [2-hydroxy-4-{[2-oxo-2-(thiophen-2-yl)ethylidene]amino}benzoic acid] and TEPC [N-[2-oxo-2-(thiophen-2-yl)ethylidene]pyridine-3-carboxamide] have been synthesized and characterized with the help of elemental analysis, magnetic, mass,1H-NMR,13C-NMR, IR and electronic spectral data. IR spectra manifest the coordination of the ligand to the metal ion through the carbonyl oxygen, azomethine nitrogen and thienyl sulphur atoms. With the help of electronic spectral data various ligand field parameters were also calculated. All these studies reveal the distorted octahedral Co(II) complexes. Synthesized compounds have also been screened against some micro organismsviz, Escherichia coli, Proteus vulgaris, Aspergillus nigerandAspergillus flavuswith the help of ‘filter paper disc’ technique. It has been observed that the antimicrobial activities of metal complexes are higher than that of the free ligand.
