Source of material
The Schiff base ligand (E)-N′-(pyridin-4-ylmethylene)isonicotinohydrazide was prepared from the condensation of isonicotinaldehyde (CAS: 872-85-5) and isonicotinohydrazide (CAS: 54-85-3) under the reflux in methanol solution. The title compound was prepared by the liquid-phase diffusion method. Firstly, 5 mL solution of (E)-N′-(pyridin-4-ylmethylene)isonicotinohydrazide (45.2 mg, 0.2 mmol) was put at the bottom of the test-tube, then, 5 mL mixed solution of methanol and 1,4-dioxane (V:V = 1:1) was layered on the previously mentioned solution. At last, 5 mL methanolic Fe(NCS)2 (0.1 mmol/L, prepared according to the literature method [6]) solution was slowly layered on the top of test-tube. After one week, red block-shaped crystals of the title compound were obtained.

Comment
Schiff base derivatives have been widely studied as complex ligands [7, 8], or catalyst-active materials [9]. Its linear dipyridine derivatives were excellent linkers for polymeric complexes [10]. However, the coordination compounds of (E)-N′-(pyridin-4-ylmethylene)isonicotinohydrazide have not been reported yet. Herein, we report the crystal structure of a 2D-grid Fe(II) polymeric compound involving the Schiff base ligand (E)-N′-(pyridin-4-ylmethylene)isonicotinohydrazide.
The Fe(II) is bridged by two (E)-N′-(pyridin-4-ylmethylene)isonicotinohydrazide linkers to form the 2D-grid layer structure. Similar networks have been already reported [11, 12]. These layers are two-fold interpenetration. The layers are interlinked to from 3D supramolecular networks by four intermolecular hydrogen bonds: N2–H2⋯O1 (symmetry code: x, −y + 1/2, z + 1/2) [length 2.00(1) Å, angle 164.37(2)°], C2–H2A⋯O1 (symmetry code: x − 1, y, z) [length 2.52(2) Å, angle 148.80(4)°], C7–H7⋯O1 (symmetry code: x, −y + 1/2, z + 1/2) [length 2.56(2) Å, angle 137.11(4)°], C2–H2A⋯N3 (symmetry code: x, −y + 1/2, z + 1/2) [length 2.66(5) Å, angle 145.13(3)°] between the layers.
