Molecular ribbons: Hydrothermal synthesis and structural characterization of [{Cu(dipic)(H2O)}2(μ-4,4' -bipy)].2H2O (dipic=pyridine-2,6-dicarboxylato; 4,4'bipy= 4,4' -bipyridyl)

Abstract

Hydrothermal reaction of Cu(OAc)₂H₂O with pyridine-2,6-dicarboxyk acid (dipicH₂) and 4,4'-bipyridine (4,4'-bipy) afforded an inorganic-organic hybrid material with an empirical

formula, C₂₄ H₁₈ O₁₀ N₄ Cu₂.2H₂O (<b>1</b>). Single crystal X-ray structure determination shows that complex (<b>1</b>) crystallized in the triclinic space group <i>P-1. </i>The unit cell contains one and a half &nbsp;molecules of [{Cu(C₇H₃NO₄)(H₂O)}₂ (C₁₀H₈N₂)].2H₂O (<b>l</b>). The crystal structure displays ribbons of (<b>1</b>) in which the 4,4'-bipy ligands are all nearly parallel. The binuclear molecules associate through hydrogen bonding and weak Cu·· ··O interactions.
