The title compound was prepared from MnCl2 · 4 H2O in the presence of KSCN and 4,4’-diaminobiphenyl (DABPh), using ethanol as a solvent. The complex was thoroughly characterized by elemental analysis, IR spectroscopy, and single crystal X-ray diffraction. The coordination mode of the SCN⁻ anion (i.e. Mn – NCS vs. Mn – SCN) was investigated, and it was found that in the solid state the manganese(II) ion is coordinated by two SCN⁻ ligands N-bonded to the metallic center. The coordination sphere around the metal also contains two DABPh and two ethanol molecules. The supramolecular structure of the complex is held together by several O – H ··· N and N – H ··· S hydrogen bonds. These interactions build up a 3D grid with the Mn atoms positioned in the corners of an 8.548 Å x 13.809 Å x 14.622 Å parallelepiped.
