A novel mixed valence copper(I)–copper(II)–bis(antipyryl-methyl)-piperazine complex: synthesis, molecular structure and spectroscopic characterization

This paper describes a new case of the bis(antipyryl-methyl)-piperazine [BAMP] ligand being in the “boat”-conformation and acting as a tetradentate. But unlike in Co(BAMP)(NCS) 2 , which is the only complex with BAMP acting as tetradentate known so far, the coordinated copper(II) is connected via a iodo-bridge to a Cu I I 2 -moiety. The synthesis, elemental analysis, spectroscopic (far- and mid-FTIR, UV–Vis) and structural characterization (X-ray diffraction) as well as magnetochemical and conductivity data of this novel mixed valence binuclear complex Cu I Cu II (BAMP)I 3 are presented.
