Synthesis and crystal structure of a novel two-dimensional 3d–4f heterometallic coordination polymer constructed from three-ply-like layers

One novel 3d–4f heterometallic coordination polymer {[ZnPr2(Dinic)4(H2O)8] · H2O}n (1) has been synthesized by hydrothermal method, where Dinic = 2,5-pyridinedicarboxylate. X-ray crystallography reveals that complex 1 possesses an interesting two-dimensional topology structure constructed from three-ply-like layers.
