چکیده
The title compound, [Ni(NCS)(2)(C(24)H(38)N(6))], 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].
