    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray diffraction; silver I compounds; solution chemistry; antibacterial activity;

    Abstract : In this thesis, new silver(I) nitrate compounds with N-donor heterocyclic ligands are described. The structures of the obtained crystalline compounds 1-19 were analysed using X-ray single-crystal diffraction. READ MORE

  7. 5. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

    Author : Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

    Abstract : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. READ MORE
