Abstract
A new lanthanide coordination polymer, {[Yb4(μ 3 -OH)4(bpdc)4(H2O)6]}2·17(H2O) (1), which contains the tetranuclear lanthanide cluster of cubane-like [Yb4(μ 3 -OH)4]8+, was obtained by hydrothermal reaction. As building blocks, [Yb4(μ 3 -OH)4]8+ clusters were further assembled into two-dimensional network structure through the linking of 2,2′-bipyridine-3,3′-dicarboxylate (bpdc) with different four coordination modes. It is unprecedented that the adjacent [Yb4(μ 3 -OH)4]8+ clusters are in the arraying form of ···AABB···(Yb1–Yb4 unit as A and Yb5–Yb8 unit as B). The thermal stability and magnetic property of compound 1 were investigated further. A new coordination polymer, {[Yb4(μ 3 -OH)4(bpdc)4(H2O)6]}2·17(H2O) was obtained by hydrothermal reaction.

The thermal stability and magnetic property of the compound were discussed further.
