Syntesis and characterisation of some mixed ligand complexes of thallium (i) metal

Kumari Seema*, Rajneesh Kumar


The present investigation has been undertaken to examine complex formation by thallium (I) derivatives of 2-nitro phenol (ONP), 2,4-dinitrophenol (DNP), 2,4,6-trinitrophenol (TNP), 1- nitroso-2-naphthol (1N2N), 8-hydroxyquinoline (8HQ), and 2-aminobenzoic acid (OABA) with thioacetamide. They have general formula [ML (L′) 2], where M = Tl (I), L = deprotonated ONP, DNP, TNP, 8-HQ, 1N2N and OABA and L′ = thioacetamide. Thioacetamide is ambidentate ligand and can donate through sulfur or nitrogen or both. The preparation of mixed ligand complex with the thallium (I) salt of o-nitrophenol and 2, 4-dinitrophenol with the thioacetamide (TAD) was unsuccessful.
