Two new Zn(II) complexes with tridentate hydrazone-based ligands (condensation products of 2-acetylthiazole) were synthesized and characterized by infrared (IR) nuclear magnetic resonance (NMR) spectroscopy single crystal X-ray diffraction methods. The 1, 2 recently [ZnL3(NCS)2] (L3 = (E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium) complex 3 tested as potential catalysts for the ketone-amine-alkyne (KA2) coupling reaction. gas-phase geometry...
In this study, a tetradentate 1,3‐propanediamine‐ N,N′- diacetate (1,3‐pdda 2− ) was utilized for the synthesis of dinuclear gallium(III) complex, uns‐ cis ‐[Ga(1,3‐pdda)( µ ‐OH)] 2 . 2H O ( 1 ). Complex characterized using IR and NMR H 13 C) spectroscopy, its crystal structure determined by single‐crystal X‐ray diffraction analysis. Both Ga(III) ions in exhibit octahedral geometry, with each ion coordinated two nitrogen oxygen atoms from 1,3‐pdda 2– ligand, as well bridging hydroxyl groups....
In this paper, Cu(II), Mn(II) and Zn(II) complexes with N,N,N-trimethyl-2-oxo-2-(2-(1-(thiazol-2-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride (HL1Cl) were synthesized characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis DFT calculations. all three complexes, a ligand (L1) is coordinated in deprotonated formally neutral zwitterionic form via NNO donor set atoms.

Abstract Two new Zn(II) complexes bearing tridentate hydrazone‐based ligands with NNO or NNS donor atoms were synthesised and characterised by elemental analysis, infrared (IR) nuclear magnetic resonance (NMR) spectroscopies, single crystal X‐ray diffraction methods. These complexes, together four previously analogues, having hydrazone a set of atoms, successfully employed as catalysts in the ketone‐amine‐alkyne (KA 2 ) coupling reaction, furnishing tetrasubstituted propargylamines,...
In solid-state coordination chemistry, the number of a metal center is not always unambiguously determined, as sometimes from geometrical parameters it clear if ligands are directly bound to central ion or they belong outer sphere complex. The nature bonding between Cu(II) and weakly coordinated anions BF4–, NO3–, ClO4– investigated by combined crystallographic computational study. It shown that synergy crystal structure determination chemistry allows identification all interactions present...
