Abstract
Two supramolecular coordination complexes, [Cu(hps)(H2O)] (1) (hps = 4-hydroxypyridone-3-sulfonic acid) and [Cu(phen)(SO4)(H2O)2] (2) (phen = 1,10-phenanthroline), have been synthesized and characterized structurally as well as magnetically. The two complexes both exhibit supramolecular networks originating from interactions such as hydrogen bonding, π–π interactions and C–HO contacts. The magnetic properties of 1 and 2 have been investigated from 1.8 to 300 K. Results indicate that 1 and 2 show antiferromagnetic interactions between Cu(ΙΙ) centers.
