cis-(1,4,8,11-Tetra­aza­cyclo­tetra­decane-[kappa]N4)bis(­thio­cyanato-[kappa]N)chromium(III) thio­cyanate

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.
