Several stable hetero-binuclear Schiff base metal complexes of nickel and strontium, (L) = N,N’-bis (salicylidene)-o-phenylenediamine; Ni(II)L = Nickle schiff base complex; Ni(II)L-Sr(II)-S1 [where, S1=ONP (o-nitrophenol)]; Ni(II)L-Sr(II)-S2 [where, S2=DNP (2,4- dinitrophenol)]; Ni(II)L-Sr(II)-S3 [where, S3=TNP (2,4,6-trinitrophenol)] have been synthesized using Ni(II) metal chelates of Schiff base and alkaline earth metal [Sr(II)] salts of ONP, DNP and TNP. The IR spectra indicate a coordination bond between the Sr(II) and the Ni(II) metal chelate, which is revealed by the oxygen atoms of the phenolic C-O. It is discovered that the nitrogen atoms of the imine and the oxygen atoms of the hydroxyl groups form an interaction between the ligands, the Nickle atom, and the strontium atom.These complexes are biologically active against bacteria viz. Gram-positive bacteria, Bacillus cereus and Staphyloccocus aureus, Gram-negative bacteria, Salmonella typhimurium and Escherichia coli, Yeast, Candida albicans, Mold, Aspergillus niger and Fungus, Aspergillus carbonarius, showing good antimicrobial and antifungal activity against several bacteria and fungi
