    COPPER(II) COMPLEX OF THE PYRAZINE-MODULATED OLIGO-α-AMINOPYRIDINE AS A COORDINATION POLYMERS’ PROMISING BUILDING BLOCK
    (Baku: Chemical Problems Journal, 2025) Ismayilova, S.Z.; Ismayilov, R.H.; Tagiyev, D.B.; Yalcin, B.; Şahin, O.; Medjidov, A.A.; Huseynova, M.T.
    Through the pyrazine-modulated tetrapyridyltriamine ligand N2-(pyrazin-2-yl)-N6-(6-(pyrazin-2ylamino)pyridin-2-yl)pyridine-2,6-diamine (H3pzpz) (1), a new mononuclear copper(II) complex [Cu(H3pzpz)(NO3)]·NO3·3H2O (2) has been synthesized and structurally characterized. The copper(II) atom in complex 2 exhibits a distorted square pyramidal geometry with an Addison parameter value of 0.39 (σ = 0.39). In compound (2), H3pzpz (1) acts as a tetradentate N4-donor ligand and coordinates to the Cu(1) ion in an anti-anti-anti-anti conformation. The single crystal X-ray analysis revealed a distorted square pyramidal geometry of the complex (2), which is consistent with the parameters of EPR spectra, measured magnetic moment susceptibility, and electronic spectrum studies. Observed extensive intermolecular hydrogen bond interactions (classical and non-classical) play an important role in the formation of the 3D supramolecular network and crystal packing of this complex. The complex (2) has been identified as a promising building block for the construction of coordination polymers. © 2025, Baku: Chemical Problems Journal. All rights reserved.

    COPPER(II) COMPLEX WITH PYRAZINE-AND TRIAZINE-MODULATED TRIPYRIDYLDIAMINE LIGAND: SYNTHESIS, CRYSTAL STRUCTURE, MAGNETIC, AND ANTIMICROBIAL PROPERTIES
    (Azerbaijan National Academy of Sciences, 2025) Ismayilova, S.Z.; Osmanli, M.H.; Ismayilov, R.H.; Tagiyev, D.B.; Huseynova, M.T.; Gahramanova, K.R.; Medjidov, A.A.
    Using the pyrazine-and triazine-modulated tripyridyldiamine ligand 6-phenyl-N2,N4-di(pyrazin-2-il)-1,3,5-triazine-2,4-diamine (H2dpztzda), a new mononuclear copper(II) complex [Cu(H2dpztzda)(NO3)2]∙2C3H7NO 1 has been synthesized, structurally characterized, and its antimicrobial properties studied. According to the single crystal X-ray analysis of complex 1, Cu(II) exhibits five coordination with a distorted trigonal bipyramidal geometry. The "inverted type" of EPR spectra (g┴ > g
