Abstract
Novel nickel(II) ethylenediamine compound, [Ni(en)3](2-chlorophenylacetate)2, has been synthesized and characterized by spectroscopic techniques (UV-vis, FT-IR), thermogravimetric analysis, magnetic moment, molar conductivity measurement, and single-crystal X-ray diffraction analysis. The complex crystallizes in a triclinic crystal system with P \(\overline{1}\) space group with cell dimensions of a = 8.9050(2), b = 12.5620(4), c = 14.0590(4) Å, α = 102.259(2)°, β = 107.172(2)°, and γ = 106.914(2)°. The complex consists of [Ni(en)3]2+ as the cationic part and two discrete 2-chlorophenylacetate ions as anionic counterparts divulging the existence of a second sphere complex with distorted octahedral geometry. Besides electrostatic forces of attraction, non-covalent interactions (hydrogen bonding and C-H…π) sew the second sphere in extended three-dimensional supramolecular architecture and provide robustness to the crystal lattice. Field electron scanning microscope (FESEM) and energy dispersive X-ray spectra (EDX) were employed to study the surface morphology of the structure. To explore the structural insights and bonding in the complex theoretical studies, i.e., density functional theory (DFT) and Hirshfeld surface analysis have also been employed.
期刊介绍:
Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry.
We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
