ABSTRACT
The salt diaquo-diammine-bis(3,4'-bi-1,2,4-triazolate) copper(II) of the formula [Cu(bTA-)2(NH3)2(H2O)2] has been synthesized and structurally characterized by X-ray single crystal diffraction analysis. This complex adopts a monomeric structure. This monomer crystallizes in the triclinic system, space group P1 with a=5.9657 Å; b=6.8975 Å; c=9.9892 Å; α=106.181°; ß=97.868°; γ=90.800° and Z=1. The Cu atom is coordinated by two nitrogen atoms of two monodentate bitriazolate ligands, two nitrogen atoms of NH3 and two water molecules in a distorted octahedral geometry. The complex has been also characterized by elemental analysis and studied by electronic and vibrational spectroscopy. The obtained results are in good agreement with the structure determined by X-ray diffraction analysis.
