Trans-{1,8-Bis[(R)-α-methylbenzyl]-1,3,6,8,10,13-hexaazacyclotetradecane}dithiocyanatonickel(II)

Abstract

The title compound, [Ni(NCS)2(C24H38N6)], is a thio­cyanate-coordinated aza­macrocyclic nickel(II) complex. There are two independent mol­ecules in the asymmetric unit and their bond lengths and angles are similar. Both Ni atoms have a tetra­gonally distorted octa­hedral geometry, in which the NiII ion is coordinated by the four secondary N atoms of the aza­macrocyclic ligand and by two N atoms of the thio­cyanate 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 inter­actions between a secondary amine N atom and the adjacent thio­cyanate ion leads to a polymeric chain along [100].
