Supramolecular assembly of ligand-directed triangular {Cu~(II)_3Cl} clusters with spin frustration and spin-chain behaviour

摘要

Triangular {Cu~(II)_3Cl} clusters, containing a chloro ligand in an unprecedented trigonal planar coordination mode, are assembled in a 3-D array by the combination of coordinative and hydrogen-bonded interactions, which result in magnetically isolated 1-D chains exhibiting a combination of spin frustration and spin-chain behaviour.
