Two CoII Compounds Showing Interesting Magnetic Properties Modulated by Supramolecular Interactions

Abstract

Two new CoII coordination compounds, namely Co[(cis-trans)-L](nip)·H2O (1) and Co[(cis-cis)-L](Hbtc)·2H2O (2) (L = N1,N4-di(pyridin-3-yl)terephthalamide, H2nip = 5-nitroisophthalic acid, H3btc = benzene-1,3,5-tricarboxylic acid), were synthesised hydrothermally and characterised by single crystal X-ray diffraction and direct current magnetic susceptibility measurement. Interestingly, the results disclose somewhat tuneable magnetic properties for compounds 1 and 2, mainly due to the distinct supramolecular interactions.
