In this work, we have obtained four new complexes Cu (II) with macrocyclic ligand tpmc (N, N', N", N"'- tetraxis (2- piridiTmethyl)- 1,4,8,11 -tetraazacyclotetra-decanes) and in the bridge connected to N, S or N, O ligands, of the general formula (Cu2 (x) tpmc) (CiO4)4 , where x= tiosemicarbaside (tsc) semicarbaside (sc), tiourea (tu) or urea (u). The obtained complexes are characterised by elementary thermal analysis, conductometry and magnetic measurement, electronic and IR spectroscopy. The values of molar conductivity in acetonitrile show 1: 4 type of electrolite. IR studies show that the ligand is bidentaly coordinated by means of N, S (tsc & tu) or N, O (sc and u ) atoms. Exo coordination of Cu (II) iones and tpmc ligands is supposed. Thermal decomposition of complexes is also done to determine thermal stability and final product of disolution. All compounds heated in the atmosphere of nitrogen are progressively disolved. Apart from that, the obtained complexes showed the microbiological activity towards some bacteria. |
