Abstract

A self-assembly reaction between the ditopic ligand 4,5-bis(tetrazol-5-yl)imidazole (H₃IBT) and cobalt(II) chloride in basic aqueous medium afforded the mixed-valence molecular species (NBu₄)₁₄ [Co^III₆ Co^II₂ (IBT)₁₂] · 22 H₂ O (1). X-ray analysis of 1 revealed a cubic arrangement of six trivalent and two divalent cobalt ions, with the latter situated on opposing vertices along the cube diagonal. The cubic coordination cluster was further characterized by cyclic voltammetry, mass spectrometry, and magnetic measurements.
