“…A medium intensity band appearing in the 2835-2970 cm -1 region corresponds to υ CH . The bands observed at 1400-1440, 1060-1080 and 710-730 cm -1 region can be assigned to phenyl ring vibrations 22 . In all of the metal complexes, a band seen in the 450-500 cm -1 region is probably due to the formation of M-N bonds 23,24 .…”

A new series of 14 membered tetraazamacrocyclic complexes of type [ML]X 2 , where M=Ni(II), Co(II), Cu(II), Zn(II), Hg(II), VO(IV), Cd(II) and Mn(II); X 2 = 2Cl-; SO 4 2-, have been synthesized by incorporating an N 4 donor site via. the template condensation of o-phenylenediamine, formaldehyde, p-anisidine and metal salt. The structural features of the complexes have been confirmed by spectral and analytical data. From the data, a square-planar geometry around the central metal ion has been suggested except VO(IV) complex which has square-pyramidal geometry. The antimicrobial screening data show good results. From the nuclease activity of the above metal complexes, it is inferred that only the copper and nickel complexes cleave DNA through redox chemistry.

“…The appearance of new bands in the 440-475 and 1,600-1,630 cm -1 ranges attributed to m(M-N) and m(C=N) vibrations, respectively [16], and the absence of m(N-H) vibrations observed in the spectra of the complexes suggest that the Schiff base product L have been formed. The [M(L)X 2 ] complexes also show bands at 1,420-1,460, 1,070-1,100 and 720-740 cm -1 which can be assigned to phenyl ring vibrations [17]. The IR spectra of the complexes show m(M-Br) bands at 220, 223 and 230 cm -1 for bromide bonded to the cobalt, nickel and zinc atoms, respectively.…”

The synthesis of a new Schiff base containing 1,10-phenanthroline-2,9-dicarboxaldehyde and 2-aminobenzenethiol subunits is described. The reaction of 1,10-phenanthroline-2,9-dicarboxaldehyde with 2-aminobenzenethiol leads to the isolation of 2,9-bis(2-benzothiazolinyl)-1,10-phenanthroline (I) which undergoes rearrangement when reacted with cobalt, nickel, copper or zinc ions to produce complexes of the tautomeric Schiff base 2,9-bis[2-(2-mercaptophenyl)-2-azaethene]-1,10-phenanthroline (L). The [Cu(L)ClO 4 ] [ClO 4 ] and [M(L)X 2 ] complexes (where M = Co(II), Ni(II) and Zn(II) and X = Br) were characterized by physical and spectroscopic measurements which indicated that the ligand is acting probably as a tetradentate N 4 chelating agent.
