Synthesis, Characterization, Crystal Structures, and Supramolecular Assembly of Copper Complexes Derived from Nitroterephthalic Acid along with Hirshfeld Surface Analysis and Quantum Chemical Studies

ACS Omega, 2023
Two new Cu(II) carboxylate complexes, Cu-NTA and Cu-DNTA, were prepared by treating 2-nitroterephthalic acid with CuSO4·5H2O at room temperature. The synthesized complexes were characterized by elemental (CHN), FT-IR, and thermogravimetric analysis.

Synthesis, Structure and Hirshfeld Surface Analysis of Phosphine–Imidazolium Salt [PDF]

Molbank, 2020
In the field of homogeneous catalysis, particularly in anti-Markovnikov hydration, sterically demanding phosphine ligand has found to be very effective. Here we report the crystal structure of a phosphine-imidazolium salt which crystallized in monoclinic space group P21/c with a = 16.6623(13) (Å), b = 10.6686(8) (Å) and c = 12.8916(11) with = 110.232(2)

Performance of 3D-space-based atoms-in-molecules methods for electronic delocalization aromaticity indices [PDF]

, 2010
Several definitions of an atom in a molecule (AIM) in three-dimensional (3D) space, including both fuzzy and disjoint domains, are used to calculate electron sharing indices (ESI) and related electronic aromaticity measures, namely, Iringand multicenter ...
