The reaction of AgCF3CO2 with nitrilotriacetate (NTA) yields the three-dimensional silver(i) coordination polymer {Ag3[N(CH2COO)3]}n 1 which was characterized by means of elemental analysis and IR spectroscopy as well as X-ray diffraction. The single crystal structure shows that the NTA3– anions act as unusual heptadentate 13-coordination agents and the silver(i) atoms exhibit various coordination numbers in the range 3–6.

Single Crystal Structure

Two Schiff base ligands Ampp-Sn1and Bmpp-Sn2, afforded by a condensation reaction between sulfanilamide and the respective acylpyrazolone carbonyl precursors, their Mn(II), Co(II), Ni(II), and Cu(II) complexes prepared by the reaction of ligands and corresponding metal salts in aqueous solutions, were synthesized and then characterized by both analytical and spectroscopic methods, in a view to developing new improved bioactive materials with novel properties. On the basis of elemental analysis, spectroscopic and TGA results, transition metal complexes, with octahedral geometry having two molecules of the bidentate keto-imine ligand each, have been proposed. The single crystal structure of Bmpp-Sn according to X-ray crystallography showed a keto-imine tautomer type of Schiff base, having three intramolecular bonds, one short N2⋯H2⋯O3 hydrogen bond of 1.90 Å and two long C13⋯H13⋯O2 and C32⋯H32⋯O3 hydrogen bonds of 2.48 Å. A moderate to low biological activities have been exhibited by synthesized compounds when compared with standard antimicrobial agents on screening the synthesized compounds againstStaphylococcus aureus,Bacillus pumilus,Proteus vulgaris, andAeromonas hydrophilafor antibacterial activity and against free radical 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) for antioxidant activity.
