Self-assembly of coordination polymers constructed from CuCN and unidentate pyridine bases

Structure and Catalytic Activity of New Metal‐Organic Frameworks Based on Copper Cyanide and Quinoline Bases

“…The cyanide groups in the MOF 1 exhibit the usual bond length of 1.164-1.175 Å, whereas the Cu-C bond lengths are 1.855 and 1.853 Å and the Cu-N(6-mquin) bond lengths are 2.068 and 2089 Å, which all are in the usual range reported for the prototype compounds. [12][13][14][15][16][17][18][19][20][21][22][23] The 1D zigzag chains are interconnected by hydrogen bonds between the carbon atom of the methyl group in the 6-mquin ligand in one chain and the hydrogen atoms of the methyl group in the 6-mquin ligand in another chain (2.726-3.178 Å), developing two dimensional sheets (Figure 2, Table 3). X-ray single crystal determination shows that the structure of 1 has a single stranded polymer Cu(CN)Cu(CN) spine, which propagates along the c axis by inversion centers located at the central CN bond, and translations, the 6-mquin ligands disposed to either side of the chain, interleaving with adjacent polymer strands and overlapping with inversion related equivalents.…”

“…[12][13][14][15][16][17][18][19][20][21][22][23] In addition, MOFs containing ligand-based hydrogen bonds (with donor-acceptor capabilities) in the structure allow the connection by hydrogen bonds whereby the dimensionality increases. These networks may present materials with advanced features since hydrogen bonds are more flexible than coordination bonds.…”

“…The monoamine CuCN-L complexes that have been reported are: (CuCN)L (L = NHEt 2 , NEt 3 , quinoline, 3-acetylpyridine (3AcOPy), 4AcOPy, 2,4,6-collidene (246Coll), ethyl isonicotinate (EIN), 2-chloropyridine, (2ClPy)), (CuCN) 2 L 3 (L = 2-methylpyridine (2MePy), 4MePy)), and (CuCN)L 2 (L = pyridine (py),3-chloropyridine (3clpy)). [12][13][14][15][16][17][18][19][20][21][22][23] All structures of these adducts are singlestranded polymers compressing sequences of copper(I) atoms linked by single end-coordinated cyanides with one or two pyridine or quinoline ligands appended with associated copper atom coordination numbers of three or four.…”

Bimetallic multidimensional supramolecular coordination polymers containing triphenyltin cation and CuCN

“…The 1 H NMR spectrum of II shows two broad overlapping peaks at 7.92 and 7.96 ppm corresponding to the aromatic protons of mpym, while the methyl protons absorb at 2.05 ppm. This assignment was supported by consulting the 1 H NMR spectrum of mpym, which exhibits sharp singlet, two doublets and one broad singlet at 8.95, 8.60, 7.45 and 2.30 ppm corresponding to H(2), H(6), H(5) and CH 3 , respectively.…”

Self-assembly and antitumor activity of an organotin coordination polymer containing a helical structure based on copper cyanide and phenanthroline ligand

“…[CuCN]-based complexes are subjected to extensive studies, especially in the presence of auxiliary N-donor bridging or chelating ligands [1][2][3][4][5][18][19][20][21][22]. When N-donor ligands are introduced into [CuCN]-based complexes, the result is a variety of coordination networks.…”
