Crystal structure of the co-crystal fac-tri­aqua­tris(thio­cyanato-κN)iron(III)–2,3-di­methyl­pyrazine (1/3)

In the crystal of the title compound, [Fe(NCS)(3)(H(2)O)(3)]·3C(6)H(8)N(2), the Fe(III) cation is located on a threefold rotation axis and is coordinated by three N atoms of the thiocyanate anions and three water mol­ecules in a fac arrangement, forming a slightly distorted N(3)O(3) octa­hedron. Stabilization within the crystal structure is provided by O—H⋯N hydrogen bonds; the H atoms from coordinating water mol­ecules act as donors to the N atoms of guest 2,3-di­methyl­pyrazine mol­ecules, leading to a three-dimensional supra­molecular framework.
