Abstract
Two novel heptanuclear trigonal prismatic LnNi 6 clusters, [SmNi 6(Gly) 6(Ac)(μ 3-OH) 3(μ 2-H 2O) 2(im) 6] · (ClO 4) 5 · (H 2O) 5 ( 1) and [GdNi 6(Gly) 6Cl 3(OH) 3(py) 6] · Cl · (ClO 4) 2 · (H 2O) 5 ( 2), were synthesized through self-assembly, and were characterized by X-ray structure analyses. Complex 1 crystallizes in the monoclinic Cc space group ( a = 17.9722(3) Å, b = 16.3906(2) Å, c = 25.3463(3) Å, β = 99.832(1)° and Z = 4). Complex 2 attributes to the monoclinic P2(1)/ c space group ( a = 15.5408(2) Å, b = 20.0516(4) Å, c = 23.8204(4) Å, β = 100.096(1)° and Z = 4). 1 has six terminal imidazole ligands, while 2 has six terminal pyridine ligands. The two complexes both have a [LnNi 6(Gly) 6(μ 3-OH) 3] 6+ core. The magnetic measurements reveal that 1 exhibits an overall antiferromagnetic interaction, while 2 exhibits a ferromagnetic interaction.
