Abstract

Mononuclear and polymeric complexes of zinc(ii) and copper(ii) have been synthesized using two isomers of the hemi-salen ligand with a different mutual orientation of donor atoms. The heterometallic Cu/Zn metallocycle features a catalytic niche filled with the molecule of water and molecules of methanol. This unusual compound exhibits both pronounced catalytic activity in the reaction of oxidation of a secondary alcohol to ketone and field induced slow magnetic relaxation, which is a very rare phenomenon among Cu(ii) complexes.

摘要

单核和聚合的锌（II）和铜（II）配合物已通过两种具有不同供体原子相互取向的半-salen 配体异构体合成。异金属 Cu/Zn 金属环具有催化龛，充满水分子和甲醇分子。这种不寻常的化合物在仲醇氧化为酮的反应中表现出显著的催化活性和场诱导的缓慢磁弛豫，这在 Cu（II）配合物中是非常罕见的现象。
