Abstract: The crystal structure of [Cr(NCS)2(cyclam)]NCS (cyclam = 1,4,8,11-tetraazacyclotetradecane, C10H24N4) has been determined by using synchrotron radiation at 98 K. The CrIII atom is in a slightly distorted octahedral environment with four N atoms of the macrocyclic ligand and two N-coordinated NCS- anions in cis positions. The average Cr-N(cyclam) and Cr-NCS bond lengths are 2.085 (5) and 1.996 (15) Å, respectively. In the crystal, the uncoordinating SCN- anion is hydrogen bonded through N-H...S and N-H...N interactions to neighbouring complex cations.
