Crystal structure of trans -(1,8-dibutyl-1,3,6,8,10,13-hexaazacyclotetradecane-κ 4 N 3 , N 6 , N 10 , N 13 )bis(perchlorato-κ O )nickel(II) from synchrotron data
Abstract
The crystal structure of the nickel(II) macrocyclic title complex, trans - [Ni(ClO 4 ) 2 (C 16 H 38 N 6 )], was analyzed using synchrotron radiation. The coordination environment consists of four nitrogen atoms from the ligand [Ni—N = 1.9382 (16), 1.9378 (17) Å] and two perchlorate oxygen atoms [Ni—O = 2.878 (3) Å], adopting an octahedral geometry with slight tetragonal distortion. The structural comparison with its Cu II analogue reveals a notable elongation in the axial Ni—O bonds, which is attributed to the steric hindrance of the macrocyclic ligand and weak axial coordination. Supramolecular interactions involving hydrogen bonding further consolidate the three-dimensional crystal packing.
