Selective Synthesis and Complexation of Novel N ,N ′-Alkylene-Bridged Bis(5-pyridyltetrazole)

A novel N , N ′‐alkylene‐bridged bis(5‐pyridyltetrazole) ligand, namely 2,5‐bis[5‐(2‐pyridyl)‐tetrazol‐2‐yl]‐2,5‐dimethylhexane (bpt), was prepared by regioselective N 2 ‐alkylation of 5‐(2‐pyridyl)tetrazole with 2,5‐dimethylhexane‐2,5‐diol in perchloric acid. The ligand bpt was found to react with copper(II) chloride to give the dinuclear complex [Cu 2 (bpt)Cl 4 ]. According to single‐crystal X‐ray analysis of the complex, bpt acts as a...
