A series of three-dimensional 3d–4f cyanide heterometallic coordination polymers: synthesis, crystal structure, photoluminescent and magnetic properties

Abstract

By the control of experimental parameters such as anions, pH value and reaction temperature, five different types of three-dimensional (3D) 3d–4f cyanide heterometallic coordination polymers (HCPs), namely [Ln3Cu7(ina)8(OAc)2(CN)6xH2O [x = 0, Ln = Nd (I-A); x = 1, Ln = Eu (I-B), Ln = Gd (I-C), Ln = Tb (I-D), Ln = Dy (I-E), ina = isonicotinate, OAc = acetate], [Ln2Cu6.5(ina)7(Cl)3(CN)2.5(H2O)6]·2H2O [Ln = Tb (II-A), Ln = Dy (II-B)], [Ln2Cu2.5(ina)3(F)2.5(SO4)0.5(CN)2(H2O)0.5] [Ln = Tb (III-A), Ln = Dy (III-B)], [Ln3Cu4.5(OH)2(ina)6(OAc)2(CN)3.5]·H2O [Ln = Tb (IV-A), Ln = Dy (IV-B)] and [Ln2Cu5.(ina)6(OAc)(CN)4(H2O)2] [Ln = Tb (V-A), Ln = Dy (V-B)] have been hydrothermally synthesized and structurally characterized. All the compounds are constructed from cyano-containing copper–inorganic motifs and Ln-containing motifs. In the type 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 I-A, I-B, I-D, II-A, III-A, IV-A and V-A, and the magnetism of I-E, II-B, III-B, IV-B and V-B were investigated.
