1 Source of materials

The ligand (1E, 2E)-1,2-bis(1-(pyridin-4-yl)ethylidene)-hydrazine (L1) was synthesized according to the literature method. 4 A methanol solution (10 mL) of ligand L1 (47.6 mg, 0.2 mmol) was carefully mixed with another methanolic solution (10 mL) containing KSeCN (28.8 mg, 0.2 mmol) and FeCl2 (12.7 mg, 0.10 mmol). The resulted solution was stirred for 1–2 min and, after filtration, the filtrate was allowed to slowly evaporate in air at room temperature. Orange block-like crystals suitable for X-ray diffraction obtained after several days were collected and air-dried. Yield: 44.7 mg (51.3 %).

2 Experimental details

Coordinates of hydrogen atoms were refined with constraints or restraints. Their U iso values were set to 1.2 U eq or 1.5 U eq of the parent atoms. For the H atom of the methanol molecules, they were refined isotropically with fixed U values, and the DFIX command was used to rationalize the bond parameter.

3 Comment

Iron(II) spin-crossover (SCO) compounds are excellent examples of heat-, pressure-, and light-induced phase transitions triggered by strong electron-phonon coupling and exhibits the great potential applications as functional materials in data storage and display devices. 5 , 6 , 7 Along with the switch between the high-spin (HS) state t2g 4 eg 2 (S = 2) and the low-spin t2g 6 eg 0 (S = 0) (LS) state in a reversible and controllable way in response to external stimuli, dramatic physical or chemical responses in crystal structure, color, optical properties, magnetism, and dielectric constant appear simultaneously, which provide useful outcomes and therefore have been given wide intention from chemists and materials scientists. 8 , 9 , 10 Here, we report the structure of a new Fe(II) complex based on a linear bidentate ligand (1E, 2E)-1,2-bis(1-(pyridin-4-yl)ethylidene)-hydrazine (L1).

As illustrated in Figure, the title neutral Fe(II) complex [Fe(L1)2(CH3OH)2(NCSe)2]·2CH3OH, which contains four units in the unit cell. The coordination environment of Fe(II) ion in the title complex is an octahedron, in which the three pairs of trans coordinate positions were occupied by two N atoms of the independent (1E, 2E)-1,2-bis(1-(pyridin-4-yl) ethylidene)-hydrazine acting as terminal monodentate ligands, two N atoms of the selenocyanato ions and two O atoms of the methanol molecules, respectively. The Fe–N L 1, Fe–NNCSe and Fe–Omethanol bond lengths are 2.189(2), 2.132(2) and 2.1030(19) Å, respectively, 11 indicating the slightly distorted octahedral sphere of the central Fe(II) ion and suggesting the paramagnetic high spin state nature of the Fe(II) ion. 12 The Fe–NC bond angle is 172.6(2)°, showing the almost linear conformation of these three atoms. It is worth noting that, depending on the strong intermolecular O–H⋯N and the O–H⋯O hydrogen bond interactions between the O atom of the solvent methanol and the N, O atoms of the host molecule, the title complex could be further constructed into interesting one-dimensional loop-like supramolecular chain structure.
