Abstract: The title mononuclear complex, [Cu(NCS)₂(C₁₀H₁₀N₄)], is located on a twofold rotation axis. The Cu^II ion assumes a tetrahedrally distorted square-planar coordination geometry. Two thiocyanate (NCS) anions and two N atoms from pyridine (py) rings coordinate in a cis manner to the Cu^II ion with a dihedral angle of 26.29 (16) Å between the Cu/N_py/N_py and Cu/N_NCS/N_NCS planes. There is a - stacking interaction between neighbouring pyridine rings [with a centroid-centroid distance of 3.7302 (14) Å and an interplanar distance of 3.311 Å] and N-HN, N-HS and C-HN hydrogen bonds.
