Synthesis And Structural Studies On Some Transition Metal Complexes Derived From Substituted Symmetric Triazines

Co (II), Ni(Il), Cu(II) and Zn(II) complexes of herbicidally active AZIPROTRYN (AZP) andrnHydrazinoethanol derivative of atrazine (HEATZ) have been synthesized from methanolicrnmedia at pH " 6. They have been characterized on the basis of analytical, thermal,rnconductance, IR spectral and electronic spectral studies. The studies show that the complexesrnare stable to atmospheric conditions and are electrolytes. The metal to ligand ratios are 1:2rnand 1: 1, respectively, for AZP and HEATZ. IR studies show that AZP is a neutral NN donorrnwhile HEATZ is a monobasic ONN donor with characteristic alkoxide bridging. Azidornnitrogen and ring nitrogen centres in AZP and alkoxide oxygen, hydrazinonitrogen and ringrnnitrogens in HEATZ have been identified as binding centres. In HEATZ alkoxide bridgingrnis a notable feature due to which the complexes achieve dinuclearity. Tetrahedral geometryrnfor Co(Il), Ni(H) and Zn(H) complexes and Equ
