Abstract:
The structural, magnetic and theoretical aspects are described for three triangular lanthanide complexes, [Tb(OH)(teaH2)3(paa)3]Cl2 (1), [Dy(OH)(teaH2)3(paa)3]Cl2 (2) and [Ho(OH)(teaH2)3(paa)3]Cl2 (3), and a hexanuclear wheel of formula [Dy(pdeaH)6(NO3)6] (4) [teaH3 = triethanolamine, paaH = N-(2-pyridyl)-acetoacetamide and pdeaH3 = 3-[bis(2-hydroxyethyl)amino]propan-1-ol]. Each complex displays single molecule toroidal behaviour as rationalised using high-level ab initio calculations. Complexes 2 and 3 are the first examples of mixed moment single molecule toroidal complexes featuring non-Kramers ions.

Synthesis Of A Ti(III) Metallocene Using Schlenk Line Technique
Inorganic chemists often work with highly air- and water-sensitive compounds. The two most common and practical methods for air-free synthesis utilize either Schlenk lines or gloveboxes. This experiment will demonstrate how to perform simple manipulations on a Schlenk line with a focus on solvent preparation and transfer. Through the synthesis of a reactive Ti(III) metallocene complex, we will demonstrate a new,...
