Dimension-related magnetism in heterometallic complexes based on the same [LnCu(dicarboxylpyrazole)2] building moieties

Interconnection of heterometallic moieties [Ln2Cu] afforded 1D ladder-like chain (in the presence of the secondary linker, SO42-) and 2D distorted trigonal lattice (without SO42-), both of which exhibited significantly different magnetic properties.295
