“…It is clear that the rational synthesis of metal cyanides with three types of electronic configurations is even more complicated. One very efficient synthetic route has been used to form heterotrimetallic species, in which stable multicyanometallates [M(CN) m ] n − may act as building blocks 18a,b,d. The [Ni(CN) 4 ] 2− complex shows a square‐planar geometry that can be considered as planar four‐connected node and it is also an environmentally friendly source of cyanide because of the slow release of cyanide under hydrothermal conditions 17b.…”

By using environmentally friendly [Ni(CN)4](2-) as a cyanide source, three new heterometallic cyano-bridged mixed-valence Cu(I)/Cu(II) coordination polymers with three different electronic configurations (d(8)-d(10)), that is, [Cu2Ni(CN)5(H2O)3] (1), [Cu2Ni(CN)5(pn)H2O] (2), and [Cu3Ni(CN)6(pn)2] (3, pn = 1,2-propane diamine) have been synthesized by gradually increasing the amount of pn. Compound 1, which was hydrothermally synthesized in the absence of pn ligand, exhibits the famous 2D Cairo pentagonal tiling, in which the Cu(I), Cu(II), and Ni(II) atoms act as trigonal, T-shaped, and square-planar nodes, respectively. Notably, there are three water molecules located at the meridianal positions of the octahedrally coordinated Cu(II) atom in compound 1. A similar reaction, except for the addition of a small amount of pn, generated a similar Cairo pentagonal tiling layer in which two of the water molecules that were located at the meridianal positions of the octahedrally coordinated Cu(II) atom were replaced by a chelating pn group. Another similar hydrothermal reaction, with the addition of a larger amount of pn, yielded compound 3, which showed a related two-fold-interpenetrated (3,4)-connected 3D framework with an unprecedented {8(3)}2{8(6)} topology in which the Cu(II) atom was chelated by two pn groups. These structural changes between compounds 1-3 can be explained by the chelating effect of the pn group. The replacement of two meridianally coordinated water molecules on the octahedral Cu(II) atom in compound 1 by a pn group gives compound 2, which shows similar Cairo tiling, and a further increase in the amount of pn results in the formation of the [Cu(NC)2(pn)2] unit and the two-fold-interpenetrated 3D framework of compound 3. The mixed-valence properties of compounds 1, 2, and 3 were confirmed by variable-temperature magnetic-susceptibility measurements.

Crystal engineering provides a powerful tool for the design and construction of coordination frameworks with unique structural motifs and tunable physical properties.[1, 2] Many heterometallic frameworks possess interesting physical properties, [3][4][5][6][7] which arise from the interactions between two distinct metal ions. However, 3D cavity lanthanide frameworks with trapped or bonded transition-metal complexes are rare. A typical strategy utilized to construct lanthanidetransition-metal frameworks is self-assembly from mixed metal ions and ligands containing hybrid donor atoms, such as carbonyl, [8] cyanide, [9] pyridine-carboxylate ligands.
