The syntheses of two new NP3 ligands containing propylene linkages, prNP3 (1) = N(CH2CH2CH2PPh2)3 and prPNetP2 (2) = (Ph2PCH2CH2CH2)N(CH2CH2PPh2)2 are reported. Using these ligands, bis(dinitrogen) complexes of molybdenum are synthesized and characterized by IR and NMR spectroscopy. The new systems are compared with the literature-known complex [Mo(N2)2(NP3)] (3) supported by the ligand NP3 [NP3 = N(CH2CH2PPh2)3], which only contains ethylene linkages. Application of the new ligand reduces the symmetry of the complex and leads to the occurrence of different isomers.

The structural, magnetic and theoretical aspects are described for three triangular lanthanide complexes, [TbIII3(OH)(teaH2)3(paa)3]Cl2 (1), [DyIII3(OH)(teaH2)3(paa)3]Cl2 (2) and [HoIII3(OH)(teaH2)3(paa)3]Cl2 (3), and a hexanuclear wheel of formula [DyIII6(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.
