Abstract

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—H⋯S hydrogen bonding. The asymmetric unit consists of one FeIII cation, four thio­cyanate anions, two coordinated pyridine mol­ecules and one pyridinium cation. The structure exhibits π–π inter­actions between pyridine rings [centroid–centroid distances = 3.7267 (2), 3.7811 (2) and 3.8924 (2) Å]. 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).
