Structural Characterization of Two Copper Complexes with 2-Arylidenebenzocycloalkanone Ligands

Resumo

Two copper complexes Cu(tta)₂(L¹)₂ (1) and Cu(tta)₂(L²)₂ (2) are synthesized and characterized by IR spectroscopy, elemental analysis, and single crystal X-ray diffraction. The copper(II) ion of 1 and 2 is in a distorted octahedral environment with four O atoms of the tta ligands and two N atoms of the heterocyclic ligands. The hydrogen bonds play important roles in stabilizing the structures.
