• Hydrogen and Halogen Bond Mediated Coordination Polymers of Chloro-Substituted Pyrazin-2-Amine Copper(I) Bromide Complexes 

  Mailman, Aaron; Puttreddy, Rakesh; Lahtinen, Manu; Svahn, Noora; Rissanen, Kari (MDPI AG, 2020)

  A new class of six mono- (1; 3-Cl-, 2; 5-Cl-, 3; 6-Cl-) and di-(4; 3,6-Cl, 5; 5,6-Cl-, 6; 3,5-Cl-) chloro-substituted pyrazin-2-amine ligands (1–6) form complexes with copper (I) bromide, to give 1D and 2D coordination ...

• Dihypoiodites stabilised by 4-ethylpyridine through O–I–N halogen bonds 

  Kramer, Eric; Yu, Shilin; Ward, Jas S.; Rissanen, Kari (Royal Society of Chemistry (RSC), 2021)

  Four bis(O–I–N) compounds have been synthesised from various dihypoiodites and 4-ethylpyridine. The compounds were characterised in both the solution and solid states by NMR spectroscopy (1H, 15N), X-ray diffraction, and ...

• Halogen Bonds in 2,5-Dihalopyridine-Copper(I) Halide Coordination Polymers 

  von Essen, C.; Rissanen, K.; Puttreddy, R. (MDPI, 2019)

  Two series of 2,5-dihalopyridine-Cu(I)A (A = I, Br) complexes based on 2-X-5-iodopyridine and 2-X-5-bromopyridine (X = F, Cl, Br and I) are characterized by using single-crystal X-ray diffraction analysis to examine the ...

• Dimeric iodine(i) and silver(i) cages from tripodal N-donor ligands <i>via</i> the [N–Ag–N]+ to [N–I–N]+ cation exchange reaction 

  Taipale, Essi; Ward, Jas S.; Fiorini, Giorgia; Stares, Daniel L.; Schalley, Christoph A.; Rissanen, Kari (Royal Society of Chemistry (RSC), 2022)

  The directionality of the [N–I–N]+ halogen bond makes iodine(I) ions impeccable tools in the design and construction of [N–I–N]+ halogen-bonded assemblies. The synthesis of dimeric iodine(I) cages with imidazole-derived ...

• Strong N−X···O−N Halogen Bonds: Comprehensive Study on N‐Halosaccharin Pyridine N‐oxide Complexes 

  Puttreddy, Rakesh; Rautiainen, J. Mikko; Mäkelä, Toni; Rissanen, Kari (Wiley-VCH Verlag, 2019)

  A detailed study of the strong N−X⋯−O−N+ (X = I, Br) halogen bonding interactions in solution and in the solid‐state reports 2×27 donor×acceptor complexes of N‐halosaccharins and pyridine N‐oxides (PyNO). Density Functional ...
