Coordination Polymer Based on a Triangular Carboxylate Core {Fe(μ 3 -O)(μ-O 2 CR) 6 } and an Aliphatic Diamine.

Interaction of the pre-organized complex of iron(II) trimethylacetate and 1,10-phenanthroline (phen) [Fe 2 (piv) 4 (phen) 2 ] ( 1 ) (piv = (Me) 3 CCO 2 - )) with 1,6-diaminohexane (dahx) in anhydrous acetonitrile yielded a 1D coordination polymer [Fe 3 O(piv) 6 (dahx) 1.5 ] n ( 2 ) and an organic salt of pivalic acid (H 2 dahx)(piv) 2 ( 3 ). The structure of the obtained compounds was determined by single-crystal X-ray diffraction analysis. The phase purity of the complexes was determined by powder X-ray diffraction analysis. According to the single-crystal X-ray analysis, coordination polymer 2 is formed due to the binding of a triangular carboxylate core {Fe 3 (μ 3 -O)(μ-piv) 6 } with an aliphatic diamine ligand. Thermal behavior was investigated for compounds 1 and 2 in an argon atmosphere.
