A semi-flexible aminotriazine-based bis-methylpyridine ligand for the design of nickel(II) spin clusters.

The self-assembly of a semi-flexible aminotriazine-based bis-methylpyridine ligand, N2,N2-dibenzyl-N4,N6-di(pyridylmethyl)-1,3,5-triazine-2,4,6-triamine (H2L), with NiCl2 and NiBr2 afforded two new nickel(II) clusters, (H2NMe2)2[Ni5(OH)2(H2L)2Cl10] (1) and [Ni6(OH)2(H2L)2Br10(THF)2] (2) showing a high spin ground state of S = 3.
