Structures and magnetic characteristics of two three-coordinate erbium(iii) compounds with C geometry, tris(2,6-di-tert-butyl-p-cresolate)erbium, Er(dbpc) (1) and tris(bis(trimethylsilyl)methyl)erbium, Er(btmsm) (2), were determined. Both underwent temperature-dependent slow magnetic relaxation processes in the absence of an external magnetic field. As a result of the differences in the coordination environment, they exhibit different energy barriers and quantum tunneling of magnetization (QTM) constants.
