资源简介：
Two new heterometallic coordination
polymers, [Na4Ln12(stp)8(OH)16(H2O)12]·10H2O [Ln
= Dy (1) and Ho (2)], have been prepared
from monosodium 2-sulfoterephthalate (NaH2stp), dysprosium
acetate, or holmium acetate. They are isostructural, possessing a
[Ln12(μ3-OH)16]20+ wheel-cluster core based on four vertex-sharing cubane-like [Ln4(μ3-OH)4]8+ units.
The Ln12 cores are linked by stp ligands into a three-dimensional
(3D) architecture. Magnetic studies indicate that complex 1 exhibits slow relaxation of magnetization, and it can be regarded
as the first 3D coordination assembly of a Dy12 cluster
single-molecule magnet.
