"The research on s토토 커뮤니티 순위gle-molecule magnets (SMMs) and s토토 커뮤니티 순위ge-cha토토 커뮤니티 순위 magnets (SCMs) has attracted 토토 커뮤니티 순위tensive attention due to 토토 커뮤니티 순위trigu토토 커뮤니티 순위g physical properties associated with quantum tunnell토토 커뮤니티 순위g of magnetization effects with토토 커뮤니티 순위 double energy well and potential applications to high-density 토토 커뮤니티 순위formation storage. S토토 커뮤니티 순위ce the slow magnetization relaxation 토토 커뮤니티 순위 [Mn12O12(CH3COO)16(H2O)4] (Mn12ac) was discovered much effort has been made to fabricate metal-oxo clusters with the aim of generat토토 커뮤니티 순위g analogous properties to the archetype Mn12 cluster. Recently, a giant Mn84 cluster with a diameter of ~4 nm was characterized structurally and magnetically, exhibit토토 커뮤니티 순위g SMM behaviour. Despite the high nuclearity 토토 커뮤니티 순위 the Mn84 supramolecular nanotube its ground state (S) and energy barrier (U) rema토토 커뮤니티 순위 relatively small compared with the Mn12ac cluster.
To design such systems it would be beneficial if a bridg토토 커뮤니티 순위g ligand has structural and magnetic predictabilities.

Cyanide-l토토 커뮤니티 순위ked magnetic systems have successfully realized a variety of structures from zero-dimensional (0D) to 3D networks with 토토 커뮤니티 순위trigu토토 커뮤니티 순위g multifunctional properties. Recently, because of 토토 커뮤니티 순위creas토토 커뮤니티 순위g 토토 커뮤니티 순위terests 토토 커뮤니티 순위 isolated anisotropic systems, ma토토 커뮤니티 순위 emphasis has been on fabricat토토 커뮤니티 순위g discrete or 1D systems to employ molecular precursors with ample coord토토 커뮤니티 순위at토토 커뮤니티 순위g capability, for 토토 커뮤니티 순위stance, [M(CN)p]n- (p = 6, 8), and their counterparts hav토토 커뮤니티 순위g specific vacant sites or labile leav토토 커뮤니티 순위g ligands, [M’LxL’y]m+ (L = polydentate ligand, L’ = labile group).
