In the title compound, [Zn(NCS)2(C24H22N4O)]·C3H7NO, the ZnII cation is N,N′,N′′-chelated by one 2-({4-[2,6-bis(pyridin-2-yl)pyridin-4-yl]phenyl}(methyl)amino)ethanol ligand and coordinated by two thiocyanate anions in a distorted N5 trigonal–bipyramidal geometry. In the molecule, the three pyridine rings are approximately coplanar [maximum deviation = 0.026 (5) Å], and the mean plane of the three pyridine rings is twisted to the benzene ring with a small dihedral angle of 5.9 (2)°. In the crystal, complex molecules are linked by weak C—H...O hydrogen bonds into supramolecular chains propagated along [110]; π–π stacking is observed between adjacent chains [centroid–centroid distance = 3.678 (4) Å]. The dimethylformamide solvent molecules are linked with the complex chains via weak C—H...O hydrogen bonds.
