posted on 2023-06-09, 08:51 authored by Khodayar Gholivand, Kaveh Farshadfer, S Mark Roe, Akram Gholami, Mehdi D EsrafiliPyridinyl carbohydrazone ligands with different positions between functional groups of –NNHC(O)– and Npy (ortho-, meta- and para-) have been applied for the synthesis of cuprous halide complexes. X-ray crystallography reveals that the ortho analogous ligand, Lo, functions in a chelating mode, adopting a mononuclear structure in complex Co, [CuClLoPPh3], while the meta and para analogs, Lm and Lp, act as ambidentate ligands, coordinating through the Npy atom in halogen-bridged binuclear complexes [Cu(µ- X)LPPh3]2 (X = Cl, Br, I and L = Lm, Lp). The influence of non-covalent intermolecular interactions on the assembly of the final structures has been discussed by geometrical and Hirshfeld analyses. Moreover, the photophysical properties of the complexes have been explored, both experimentally and theoretically. The influence of ligand structure and halide variations on the structural and photophysical aspects of the complexes has been considered in this study.
