Synthesis and structure of a new copper(II) complex with 3,4′-bi-1,2,4-triazolate
摘要:
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 P (1) over bar with a = 5.9657 angstrom; b = 6.8975 angstrom; c = 9.9892 angstrom; alpha = 106.181 degrees; beta = 97.868 degrees; gamma = 90.800 degrees 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. (C) 2010 Elsevier B.V. All rights reserved.
