In the title compound, (C5H6N)[Fe(NCS)4(C5H5N)2], the FeIII ion is coordinated by four thiocyanate N atoms and two pyridine N atoms in a trans arrangement, forming an FeN6 polyhedron with a slightly distorted octahedral geometry. Charge balance is achieved by one pyridinium cation bound to the complex anion via N—HS hydrogen bonding. The asymmetric unit consists of one FeIII cation, four thiocyanate anions, two coordinated pyridine molecules and one pyridinium cation. The structure exhibits – interactions between pyridine rings [centroid–centroid distances = 3.7267 (2), 3.7811 (2) and 3.8924 (2) A˚ ]. The N atom and a neighboring C atom of the pyridinium cation are statistically disordered with an occupancy ratio of 0.58 (2):0.42 (2).

Identification of the privileged position in the imidazo[1,2-a]pyridine ring of phosphonocarboxylates for development of Rab geranylgeranyl transferase (RGGT) inhibitors Kaźmierczak, Aleksandra; Kusy, Damian; Niinivehmas, Sanna; Gmach, Joanna; Joachimiak, Łukasz; Pentikäinen, Olli; Gendaszewska-Darmach, Edyta; Blazewska, Katarzyna M. (American Chemical Society, 2017)Members of the Rab GTPase family are master regulators of vesicle trafficking. When disregulated, they are associated with a number of pathological states. The inhibition of RGGT, an enzyme responsible for post-translational ...
Kiesilä, Anniina; Moilanen, Jani O.; Kruve, Anneli.; Schalley, Christoph A.; Barran, Perdita; Kalenius, Elina (Beilstein Institut zur Foerderung der Chemischen Wissenschaften, 2019)Pyridinearenes have previously been considered as anion binding hosts due to the electron-poor nature of the pyridine ring. Herein, we demonstrate the encapsulation of Me4N+ cations inside a dimeric hydrogen-bonded ...
