] [Ln = Tb (

I
structures, the copper-inorganic motifs can be viewed as double-stranded {Cu(CN)}
∞
ribbons with projecting sidearms, and the Ln-organic motifs are zigzag chains. In the type
II
structures, the copper-inorganic motifs are two-dimensional (2D) {CuCl(CN)}
∞
layers, while the Ln-organic motifs can be described as two kinds of very similar one-dimensional (1D) chains possessing a parallel and alternating arrangement. In type
III
structures, the copper-inorganic motifs are 2D layers whereas the Ln-organic/inorganic motifs are fluoride-bridging 2D layers. In the type
IV
structures, the copper-inorganic motifs contain two unique types of 0D copper-cyanide units, while the Ln-organic counterparts are 1D chain structures linked by OH
−
groups. In type
V
structures, the copper-inorganic motifs and the Ln-organic motifs are 2D layers that can both be topologically simplified to (4, 4) networks. Moreover, the photoluminescence of

Five different types of novel three-dimensional (3D) 3d-4f cyanide heterometallic coordination polymers are synthesized. All the compounds are constructed from cyano-containing copper-inorganic motifs and Ln-containing motifs. |
