Using the flexible ligand bis(2-hydroxyethyl)amino-tris (hydroxymethyl)methane ("bis-tris") to access a family of 3d-4f Mn(III)4Ln4 complexes.

A series of isostructural 3d-4f coordination clusters (CCs) [Mn(4)Ln(4)(OH)(6)(H(2)L)(2)(H(3)L)(2)(PhCO(2))(2)(N(3))(2)(MeOH)(4)]Cl(1.6)(N(3))(0.4)(NO(3))(2)·2.4H(2)O·1.6MeOH where Ln = Gd, Tb, Dy, Ho and Er and H(5)L = bis(2-hydroxyethyl)amino-tris(hydroxymethyl)methane (bis-tris) has been synthesised and structurally characterised. The paramagnetic metal… (More)
