title: (2,9-Dieth-oxy-1,10-phenanthroline-κN,N')bis-(thio-cyanato-κN)cobalt(II).
abstract: In the title complex, [Co(NCS)(2)(C(16)H(16)N(2)O(2))], the Co(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline ligand and two N atoms from two different thio-cyanate ligands in a distorted tetra-hedral environment. The Co-N bonds involving the thio-cyanate ligands are significantly shorter than the other two Co-N bonds. The atoms of one of the eth-oxy groups are essentially coplanar with the phenanthroline ring [N=C-O-C = 178.8 (4)°], while the other eth-oxy group is slightly twisted from the phenanthroline ring plane [N=C-O-C = 167.2 (4)°]. In the crystal structure, there is a weak π-π stacking inter-action between two symmetry-related phenanthroline rings with a centroid-centroid distance of 3.706 (4) Å.
