title: Novel mixed-valent Co(II)₂Co(III)₄Ln(III)₄ aggregates with ligands derived from tris-(hydroxymethyl)aminomethane (Tris).
abstract: Isostructural Co(II)₂Co(III)₄Ln(III)₄ (Ln = Y (1), Gd (2) and Dy (3)) coordination clusters formed using the ligand Tris are the first examples of 3d-4f complexes involving this ligand and show weak ferromagnetic coupling between the Co(II) ions and slow relaxation (SMM) behaviour for 3.
