A new binuclear copper(II) complex [Cu2L2] was synthesized via in situ aqua doubly deprotonated ligand substitution reaction, forming a zig-zag coordination polymer (CCP). The crystal structure was specified by XRD method, showing a five-coordinated distorted tetragonal pyramidal geometry for the Cu(II) center. The desired CCP structure chains were connected into a 2D-supramolecular assembly through C-H...O H-bond and pi-pi stacking interactions, leading to the formation of super thermal CCP complexes.
New binuclear copper(II) complex [Cu2L2] zig-zag coordination polymer (CCP) have been synthesized via one-pot copper(II) acetate/(E)-2-((2-hydroxynaphthalen-1-yl)diazenyl)benzoic dye through an in situ aqua doubly deprotonated ligand substitution reaction. The coordination polymer complex was characterized by spectroscopic and CHN-elemental analysis. The crystal structure has been specified by the XRD method exhibiting that the Cu(II) center geometry is with five-coordinated distorted tetragonal pyramidal. The desired CCP structure chains are connected into a 2D-Supramolecular assembly via one C-H...O H-bond and enhanced by a pi-pi stacking interactions. These interconnections strengthened the lattice of CCP that originated the formation of super thermal CCP complexes. The fundamental vibrational wavenumbers and electron transfer in the free ligand are combined with the complex before and after coordination to demonstrate the spectral behavior of L-2 in the desired zig-zag CCP. The 2D-fingerprint (2D-FP) and Hirshfeld surface analysis (HSA) computations were served to prove the 2D-network packed crystal lattice interactions. (C) 2020 Elsevier B.V. All rights reserved.
