Five novel copper(II) coordination polymers containing cyanoacetate (cna) anion with various N,N'-ditopic spacers [Cu(cna) 2 (pyz)] n (1), [Cu(cna) 2 (bpy)(H 2 O) 2 ] n (2),[Cu(cna) 2 (dpe)] n (3), [Cu(cna) 2 (dpe)] n (H 2 O) n (4) and [Cu(cna) 2 (bpa)] n (5) (when pyz = pyrazine, bpy = 4,4'-bipyridyl, dpe = 1,2-di(4-pyridyl)ethylene and bpa = 1,2-di(4-pyridyl)ethane) were structurally and spectroscopically characterized. Compound 1 shows 2D sheet structure constructed from µ 2 -1,3(syn,anti) coordinative mode of cyanoacetate and µ 2 -pyz linking adjacent Cu(II) centers. Compound 2 exhibits 1D polymeric chain which is formed by µ 2 -bpy bridging between [Cu(cna) 2 (H 2 O) 2 ] units. Whereas compounds 3-5 reveal 1D ladder-like structures which are built from double-µ 2 -dpe/bpa spacers connecting neighboring Cu(II) cyanoacetate dimers.Weak interactions such as hydrogen bonding and N···π and/or C−H···π interactions join the adjacent layers of 1 or polymeric chains of 2-5 to stabilize overall supramolecular networks. The thermal stabilities of 1-5 were investigated. Interestingly, compound 2 reveals a robust supramolecular framework constructed by 1D polymeric chains during thermal dehydration and rehydration processes, that has been further verified by spectroscopic techniques, elemental analyses, TGA, and XRPD. Moreover, this behavior is not observed in the isomorphous series containing Co(II) and Ni(II) ions. The magnetic properties of 1 and 3 exhibit very weak antiferromagnetic interactions between Cu(II) centers.

“…corroborate the rhombic and, since this compound is centrosymmetric, a planar (dihedral angle of 0.0°) geometry of the dimer. The distance between Cu⋯Cu ions is 3.33 Å, which is larger than those found for paddle-wheel type compounds (2.58-2.65 Å) [27], although it is closer to those originated in complexes having bridging Cu-O-Cu square dimeric clusters (3.05-3.12 Å) [28,29]. The two Cu centers are doubly bridged by the O atoms of the two chelatingbridging maleates (Fig.…”

Synthesis and crystal structure of a 3D copper(II)-silver(I) coordination polymer assembled through hydrogen bonding, π-π stacking and metal-π interactions, {[Cu(phen) 2 (CN)][Ag(CN) 2 ] · 3H 2 O} n (phen = 1,10-phenanthroline)[Ag(CN) 2 ] · 3H 2 O} n , 1 (phen = 1,10-phenanthroline), has been prepared and structurally characterized. The compound crystallizes in the monoclinic space group P2 1 /c with [Cu(phen) 2 (CN)] + and [Ag(CN) 2 ] − units and three water molecules. The cationic and anionic units are linked to each other through M-π and π-π interactions. The array is extended further by hydrogen bonding and π-π interactions to form a 3D network.
