Magnetic behavior of the novel pentagonal-bipyramidal erbium() complex (EtNH)[Er(HDAPS)Cl]: high-frequency EPR study and crystal-field analysis
We report the synthesis, crystal structure and magnetic properties of the new heptacoordinated mononuclear erbium( iii ) complex (Et 3 NH)[Er(H 2 DAPS)Cl 2 ] (H 4 DAPS = 2,6-diacetylpyridine bis-(salicylhydrazone)) ( 1 ). The coordination polyhedron around the Er( iii ) ion features a slightly disto...

-values of the three lowest Kramers doublets (KDs) of the Er(
