| dc.description.abstract | Co (II), Ni(Il), Cu(II) and Zn(II) complexes of herbicidally active AZIPROTRYN (AZP) and Hydrazinoethanol derivative of atrazine (HEATZ) have been synthesized from methanolic media at pH " 6. They have been characterized on the basis of analytical, thermal, conductance, IR spectral and electronic spectral studies. The studies show that the complexes are stable to atmospheric conditions and are electrolytes. The metal to ligand ratios are 1:2 and 1: 1, respectively, for AZP and HEATZ. IR studies show that AZP is a neutral NN donor while HEATZ is a monobasic ONN donor with characteristic alkoxide bridging. Azido nitrogen and ring nitrogen centres in AZP and alkoxide oxygen, hydrazinonitrogen and ring nitrogens in HEATZ have been identified as binding centres. In HEATZ alkoxide bridging is a notable feature due to which the complexes achieve dinuclearity. Tetrahedral geometry for Co(Il), Ni(H) and Zn(H) complexes and Equ<:rc plnnar geometry 'for eu(n) conipieicof AZP have been proposed. Based on electronic spectral studies, Co(H), Ni(H), CU(ll) complexes with the composition [M2L2(H20),lCI2 (L = HEATZ) have been adjudged octahedral. Thermochromism has been observed with cobalt (II) complex of HEATZ. It is pink in colour at room temperature, but changes to green through a transient blue colour as it is heated to 220°C. Preliminary antimicrobial studies on E. coli and S. aureus have been done using AZP, ATZ, HEATZ, metal salts, complexes and related compounds | en_US |
