The slow magnetic relaxation observed in a mixed carboxylate/hydroxide-bridged compound [Co2Na(4-cpa)(2)(mu(3)-OH)( H2O)](infinity) featuring magnetic D-chains

摘要

Magnetic Delta-chains in a 3D coordination polymer [Co2Na(4-cpa) (2)(mu(3)-OH)(H2O)](infinity) are well separated by Na+ ions and organic spacers, and exhibit not only magnetic behaviour of Delta-chain topology but also slow magnetic relaxation.
