Abstract
A copper(II)/potassium(I) Schiff base polymeric complex has been synthesized and characterized. Salen-type N2O2O2′ donor compartmental Schiff base ligand has been used where copper(II) resides in the inner N2O2 core and potassium (I) sits in the outer O2O2′ core. Single crystal X-ray analysis revealed that the unintended formation of a disordered bromine atom led to Cu⋯Br π-hole coinage bond (CiB) interaction. The energetics regarding the CiB interactions have been rationalized using DFT calculations, QTAIM, and ELF study.
期刊介绍：
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
