A Surprising Example of Crystal Structure Retention for 3,5-Di-(tert-butyl)-2-hydroxyazobenzene Ligand during the Formation of Ni(II) and Pd(II) Complexes

The structures of 3,5-di-( tert -butyl)-2-hydroxyazobenzene (L) in the free state and in complexes with Ni 2+ ( I ) and Pd 2+ ( II ) cations are studied by X-ray diffraction (XRD). The same space group R с with close unit cell parameters, the same crystal structure motif, and unusual conformations o...

Summary:The structures of 3,5-di-( tert -butyl)-2-hydroxyazobenzene (L) in the free state and in complexes with Ni 2+ ( I ) and Pd 2+ ( II ) cations are studied by X-ray diffraction (XRD). The same space group R с with close unit cell parameters, the same crystal structure motif, and unusual conformations of the cupola-shaped coordination polyhedra of complexes I and II are revealed by XRD for ligand L. In complexes I and II based on this compound as the ligand, the coordinating atoms form trans -planar coordination nodes.
