Title : Chemistry of Zn Complexes with different Non Covalent Interactions


Study of non-covalent interactions is the main piller of supramolecular chemistry. Mostly it plays an important role in controlling the physical property as well as structural topology. In order to explore that role a series of four mononuclear Schiff-base complexes, namely, [Zn(L)(NCS)2] (1), [Zn(L)(N3)2] (2), [Cu(L)(NCS)2] (3) and [Ni L)(2bpy)(NCS)](ClO4) (4), [where L = N,N-dimethyl-N′-

(phenyl-pyridin-2-yl-methylene)-ethane-1,2-diamine and 2bpy = 2-benzoylpyridine] were synthesized and the role of different non-covalent weak interactions responsible for the crystal packing of the complexes were thoroughly investigated. All of them were structurally characterised by X-ray diffraction analysis. In addition to conventional CH3 …….. π and π…..π interactions, the importance of unconventional C–H ……π interactions in the crystal packing of compounds 1–4 was investigated by means of Hirshfeld surface analysis and DFT calculations. In these unconventional C–H…….π interactions, the π-system (electron donor) is provided by the pseudohalide coligands. The interactions formed by the π-system depend on the nature of the pseudohalide (N3, NCO, NCS or NCSe) as demonstrated by molecular electrostatic potential calculations. Additionally, we have explored the photophysical properties of these complexes. Finally, we have combined a search in the Cambridge Structural Database and DFT energy calculations to analyse the rare ambidentate behaviour of SCN within the same complex.

Audience take-away:

  • By explaining different weak interactions present in the complexes audience will be able to learn the behavior of different pseudohalide moiety in formation of the complexes.
  • The audience will learn the synthetic methodology of above mentioned coordination complexes.
  • This research will help to understand the interactive behavior of pseudo halide chemistry.
  • The simple synthetic strategy will help researchers to develop such coordination complexes in no time.


Dr. Prateeti Chakraborty studied Chemistry at Bethune College affiliated to University of Calcutta and graduated in 2007. She then did her master’s from the same university in the year of 2009. After completing her post graduate study she joined the research group of Prof. Das at University of Calcutta and received her PhD degree in 2015. After 1 years of postdoctoral research in the same lab on Zn Chemistry, Catalysis she Joined Sharda University , Greater Noida as an Assistant Professor. Presently, she is working as an Assistant Professor in Chemistry at Bangabasi College. She has published 4 book chapters with an International Publisher and more than 35 research articles in journals of International repute.
