Mixed ligand complexes of the type M2L(Im)4X4 [L = N,N’ -bis(4-antipyrilmelhyl)piperazine (BAMP) or N,N’-tetra(4-antipyrilmethyl)-1,2-diaminoethane (TAMEN), Im = imidazole, X = NCS, CIO-, M = Co, Cu] were synthesized and investigated by UV-VIS, IR and Raman spectroscopy, magnetic measurements at room temperature and electrical conductivities. The IR and Raman spectra revealed that the ligands L are coordinated through the carbonyl O atom of the antipyrine and the N atom of the piperazine of 1,2-ethanediamine. Imidazole is bonded through the Sp2 nitrogen atom. The compound of [Co(BAMP)(Im)(H2O)2](ClO4)2 has been studied by X-ray method, the cell parameters are a = 20.662(2); b = 7.145(3); c = 26.180(2) Å; β = 91.54º; space group is Cc. The coordination polyhedron of the Co atom is tetrahedral pyramid and this compound forms in the crystal polymeric structure where complexes are connected via the piperazine molecule as a bridge. |
