Structure and magnetism of a binuclear Cu II pyrophosphate: Transition to a 3D magnetic behaviour studied by single crystal EPR

Mostrar todas las versiones(2)

A binuclear Cu II compound [Cu 2 (bpa) 2 (P 2 O 7 )(H 2 O) 2 ]·2.5H 2 O, 1, (bpa = 2,2′-bipyridylamine), with pairs of Cu II ions bridged by one pyrophosphate tetra-anion, was synthesized and crystallized. Its triclinic structure was determined by single-crystal X-ray diffraction. Electron paramagne...
