摘要

The asymmetric unit of the title compound, [Fe(NCS)2(C6H4N2)2(H2O)2]·2C6H4N2, comprises one FeII cation occupying an inversion centre as well as one thio­cyanate anion, one water mol­ecule and two 4-cyano­pyridine mol­ecules in general positions. The iron cations are coordinated by two N-bonded thiocyanate anions, two (pyridine)N-bonded 4-cyano­pyridine ligands and two water mol­ecules into discrete complexes. The resulting coordination polyhedron can be described as a slightly distorted octa­hedron. The discrete complexes are connected through centrosymmetric pairs of (pyridine)C—H⋯N(cyano) hydrogen bonds into chains that are further linked into a three-dimensional network through inter­molecular O—H⋯N hydrogen bonds involving the 4-cyano­pyridine solvent mol­ecules.
