In the crystal structure of the title compound, [Ni(C 31 H 22 Cl 2 N 4 O 2 )], the Ni atoms are coordinated by four N atoms of the macrocyclic ligand in a distorted square-planar configuration. Three C atoms are disordered over two positions, with site occupancy factors of 0.85 and 0.15. Related lit

## Abstract The molecular structures of the title compounds 3 and 5 were investigated by NMR and X‐ray structural methods. The NMR results suggest two equivalent halves for both molecules. The X‐ray study shows an approximate mirror plane for 3 and an approximate twofold axis for a significant port
2,7 ]tridecan-13-one reacts with 2-aminobenzyl alcohol to form the title compound, C 26 H 29 NO, which crystallizes with two independent molecules in the asymmetric unit. The N atom shows a nearly planar coordination owing to the strain imposed on the fused-ring compound.
