Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The cobalt(II) coordination polymer [Co(ADN)₃][FeCl₄]₂ (<bold>1</bold>), which contains a flexible dinitrile bridging ligand was synthesized at room temperature from the 1:2:3 reaction of CoCl₂, FeCl₃, and adiponitrile (ADN) in CH₃NO₂. The compound was characterized by spectroscopic methods and single‐crystal X‐ray diffraction. The structure of <bold>1</bold> consists of a 2D sheet structure of [Co(ADN)₃]²⁺ cations, the charge balance is maintained by [FeCl₄]^– anions. Each central Co^II atom is coordinated by six nitrogen atoms from four <italic>gauche</italic>‐ and two <italic>anti</italic> ligands, adopting a distorted octahedral arrangement. The [FeCl₄]^– anions sit in channels created by the [Co(ADN)₃]²⁺ cations, and link the 2D sheets into a 3D structure by weak C–H<bold>···</bold>Cl hydrogen bonds. The framework structure of <bold>1</bold> is thermally stable up to 285 °C.</p> </abstract>
