Heterobinuclear Zn–Ln and Ni–Ln Complexes with Schiff‐Base and Carbacylamidophosphate Ligands: Synthesis, Crystal Structures, and Catalytic Activity

Abstract

Abstract The reaction of Salen‐like Zn II and Ni II precursors with carbacylamidophosphate lanthanide moieties yields six new types of 3d–4f compounds. The complexes were characterized by means of 1 H, 31 P NMR and IR spectroscopy, elemental analysis, ESI mass spectrometry, and X‐ray diffraction analysis. Depending on the Schiff base ligands, the Ni II ion adopts either a square‐planar or an octahedral geometry, whereas the Zn II ion has a tetragonal‐pyramidal geometry. The coordination number of lanthanides is nine or ten. Hydrolytic activities of some heterobimetallic Zn–Ln and Ni–Ln coordination compounds in the reaction of intramolecular hydrolytic degradation of the 2‐(hydroxypropyl)‐ p ‐nitrophenyl phosphate were investigated.
