Tapping into the secondary coordination environment of mononuclear DyIII-complexes leads to drastic changes in luminescence and magnetism. Visualization of effects induced by stereoelectronics on the opto-magnetic properties was achieved through subtle modifications in the ligand framework.

series of mononuclear lanthanidecomplexes. The employed N-2-pyridylimidoyl-2-pyridylamidine (Py2ImAm) undergoes metal-assisted hydrolysis yielding the ligand 2-amidinopyridine (PyAm), which coordinates to the lanthanide ions affording [Ln(acac)3(PyAm)], where Ln = Eu(III) (1), Gd(III) (2), Tb(III) (3), Dy(III) (4) along with the Y(III) analogue (5). The Eu(III), Tb(III), and Dy(III) congeners exhibit

Fe, and Co in coordination complexes with the ligand N-2-pyridylimidoyl-2-pyridylamidine (Py2ImAm), which possesses both a bidentate and tridentate coordinating site. The synthesis and characterization of seven new metallic complexes are described, and these results indicate that the key factor dictating which coordination site of Py2ImAm the metalion prefers is the presence (or absence) of a weak
