Abstract: In the title complex, [Co(NCS)₂(C₁₆H₁₆N₂O₂)], the Co^II ion is coordinated by two N atoms from one 2,9-diethoxy-1,10-phenanthroline ligand and two N atoms from two different thiocyanate ligands in a distorted tetrahedral environment. The Co-N bonds involving the thiocyanate ligands are significantly shorter than the other two Co-N bonds. The atoms of one of the ethoxy groups are essentially coplanar with the phenanthroline ring [N=C-O-C = 178.8 (4)°], while the other ethoxy group is slightly twisted from the phenanthroline ring plane [N=C-O-C = 167.2 (4)°]. In the crystal structure, there is a weak - stacking interaction between two symmetry-related phenanthroline rings with a centroid-centroid distance of 3.706 (4) Å.
