Abstract

The CoIII ion in the title compound, [Co(NCS)2(C16H32-N4)](SCN), is six-coordinate in a distorted octahedral environment, with the four N atoms of the macrocyclic tetradentate ligand equatorial and the N atoms of two isothiocyanato groups axial. The tetradentate macrocyclic ligand is in a planar conformation, with the two five-membered rings in gauche conformations and the two six-membered rings in twist conformations. The complex has an RR or SS configuration for the two chiral amine N centres. Intermolecular hydrogen bonds between the two NH groups and the unbonded thiocyanate anion help stabilize the crystal structure.
