Trans-{1,8-Bis[(R) α- Methyl-benz-yl]-1,3,6,8,10,13-hexa-azacyclo- tetra-deca-ne}dithio-cyanato-nickel(II)

The title compound, [Ni(NCS)2(C24H38N6)], is a thio-cyanate-coordinated aza-macrocyclic nickel(II) complex. There are two independent mol-ecules in the asymmetric unit and their bond lengths and angles are similar. Both Ni atoms have a tetra-gonally distorted octa-hedral geometry, in which the Ni ^II ion is coordinated by the four secondary N atoms of the aza-macrocyclic ligand and by two N atoms of the thio-cyanate ions. The average equatorial Ni - N bond lengths are shorter than the average axial Ni - N bond lengths [2.071 (1) and 2.115 (2) Å, respectively]. N - H⋯S hydrogen-bonding inter-actions between a secondary amine N atom and the adjacent thio-cyanate ion leads to a polymeric chain along [100].
