Abstract:

Five novel heptanuclear trigonal-prismatic polyhedra, Na4[Pr- Ni6(Gly)9(μ3-OH)3 (H2O)6] · (ClO4)7 (1), Na2[PrNi6(Gly)8(μ3- OH)3(μ2-OH2)- (H2O)6 · (ClO4)6 · (H2O)2 (2), Na- [DyNi6(Gly)7(μ3-OH)3 (μ2-OH2)2(H2O)6] · (ClO4)6 · H2O (3), [SmNi6(Gly)6- (μ3-OH)3Cl3(H2O)6] · Cl3 · (H2O)9 (4), and [ErNi6(Gly)6(μ3- OH)3Cl3(H2O)6] · Cl3 · (H2O)9 (5), were synthesized through self-assembly and characterized by X-ray structure analysis. Complex 1 crystallizes in the trigonal P3 space group (a=b=18.1121(2), c= 11.987(0) A, and Z=2). Complex 2 belongs to the triclinic P1 space group (a=16.0145(3), b=20.58650(10), c= 20.8452(3) A, α=78.0590(10), β= 67.9200(10), γ=68.1540(10)°, and Z= 4). Complex 3 belongs to the monoclinic P2(1)/m space group (a=14.9863(3), b=13.533, c=15.6171(3) A, β= 116.8970(10)°, and Z=2). Complexes 4 and 5 are isomorphous (4: trigonal, P3; a=b=11.8661(4), c = 18.2034(10) A, Z=2; 5: a=b=11.9001(5), c = 18.1229(11) A, Z=2). A Ln3+ ion is in the center of the prism formed by six nickel atoms. It coordinates to nine oxygen atoms. Its coordination polyhedron may be best described as a tricapped trigonal prism. The five complexes all have a core of [LnNi6(Gly)6- (μ3-OH)3(H2O)6]6+ and were obtained through the edge-ligand exchange of the three μ2-OH2 ligands of [LnNi6(Gly)6- (μ3-OH)3(H2O)6 (μ2-OH2)3]6+ partly or wholly by glycine or Cl-. Magnetic measurements reveal that 1 and 4 exhibit antiferromagnetic interaction, while 5 exhibits a ferromagnetic interaction.
