Coordination Chemistry

We are developing synthesis methods for new complex compounds of d-block metals used in modern technologies and medicine. Currently, we are conducting research on coordination compounds containing Cd2+, Zn2+, Co2+, Ni2+, Cu2+, Ag+ , and Au3+ cations, along with selected S- and N-donor ligands, such as:

  • silanethiolate ligands derived from two silanethiols TBST and TDST [1,2], which we use for the synthesis of Cd2+, Zn2+ complexes with luminescent properties [3,4] and for the synthesis of Co2+ and Ni2+ complexes with molecular magnet properties [5],
  • nitrile ligands, used by us for the synthesis of complexes that release Ag+ and Au3+ ions with strong antimicrobial activity [6],
  • imidazole and its derivatives, forming molecular complexes with metal ions, reflecting the way metal ions bind to proteins [7,8], and, after deprotonation of imidazole, materials with polymer-like properties (ZIF); the latter show good sorption and catalytic properties [9],
  • Schiff bases (imines); we study imine compounds with Zn2+, Co2+, Ni2+, Cu2+ ions as catalysts in organic compound oxidation reactions [10] and as potential anti-cancer drugs [11],
  • derivatives of strongly luminescent thiazolothiazoles; coordination compounds of thiazolothiazole ligands and selected metal ions will be tested as components with memristor properties [12]
