“…These can take the form of simple monomers L 2 Cu(CO)X (X = Cl, I, ClO 4 , OTf) , or anion-bridged dimers L 2 Cu(CO)(μ-X)Cu(CO)L 2 + (X = Cl, Br, I, ClO 4 ). ,, Copper(I) tends to form rhomboid dimers via the bridging of halide ions (Cu(μ-X) 2 Cu). These dimers have been strung into linear polymers using bridging diamines in the presence of CO to form polymers ( IX ) . Although copper readily forms bridging arrangements with other metal carbonyls during cluster formation, only a few clusters containing homonuclear μ 2 -C,C Cu 2 (μ 2 -CO) complexes are known.…”

The coordination chemistry of copper(I) carbonyls and cyano complexes is reviewed. Primary attention is focused structural chemistry, including coordination behavior, bridging modes, network formation, flexible coordination number, and reversible ligand binding. Additional coverage of infrared spectroscopy and orbital interactions in carbonyl and cyanide bonding, and photophysical behavior of metal cyano complexes is also included. BRIEF The coordination chemistry of copper(I) carbonyls and cyanide complexes is reviewed.

“…Networks produced from metal salts of bridging anions, such as halides and pseudohalides, can be effectively used to avoid the problem of counterions filling pores. We have recently been studying network materials derived from copper(I) halides . However, the resistance of copper(I) halides toward oxidation is modest at best.…”

Metal-organic networks of CuCN with diimines (L) = pyrazine (Pyz), 2-aminopyrazine (PyzNH(2)), quinoxaline (Qox), phenazine (Phz), 4,4'-bipyridyl (Bpy), pyrimidine (Pym), 2-aminopyrimidine (PymNH(2)), 2,4-diaminopyrimidine (Pym(NH(2))(2)), 2,4,6-triaminopyrimidine (Pym(NH(2))(3)), quinazoline (Qnz), pyridazine (Pdz), and phthalazine (Ptz) were studied. Open reflux reactions produced complexes (CuCN)(2)(L) for L = Qox, Phz, Bpy, PymNH(2), Pym(NH(2))(2), Qnz, and Pdz and (CuCN)(3)(L) complexes for L = Pyz, PyzNH(2), Qox, Bpy, Pym(NH(2))(3), and Pdz. Also produced were (CuCN)(3)(Pyz)(2), (CuCN)(PyzNH(2)), (CuCN)7(Pym)(2), (CuCN)(5)(Qnz)(2) and (CuCN)(5)(Ptz)(2). X-ray structures are presented for (CuCN)(2)(Pdz), (CuCN)(2)(PymNH(2)), and (CuCN)(7)(Pym)(2). Hydrothermal reactions yielded additional X-ray structures of (CuCN)(2)(PyzNH(2)), (CuCN)(3)(Pym(NH(2))(2)), (CuCN)(4)(Qnz), a second (CuCN)(2)(Pdz) phase, (CuCN)(5)(Pdz)2, (CuCN)(2)(Ptz), and (CuCN)(7)(Ptz)2. Structural trends, including cuprophilic interactions and cyano-bridged Cu(2)(CN)(2) dimer formation, are discussed. Particularly short Cu...Cu interactions are noted for the novel 4- and 5-coordinate Cu(2)(CN)(2) dimers. Thermal analyses show that most of the complexes decompose with loss of L around 160-180 degrees C. Luminescence behavior is relatively weak in the products.

The number of CuCl units per camphor ligand in [{CuCl} 2 L] n was extended to three or four in [{CuCl} 3 L] n (2) or [{CuCl} 4 L] n (1). The Hartree-Fock ab initio calculations support the polymeric structure of 1 and 2 that catalyze the cyclization of 4-pentyn-1-oic acid (A) forming 5-methylenedihydrofuran-2(3H)-one (B) and/or 2-methyl-5-oxotetrahydrofuran-2-ylpent-4-ynoate (C). The catalytic activity of 1, 2 and other polynuclear Cu(I) complexes (3-5) was evaluated under solvent free conditions and/or solution. In the absence of solvent, catalyst 2 displays the highest activity and selectivity (75.8/23.1, C to B ratio, at 5.4% loading) while 4 reaches the highest level of A ! B conversion (97.5 %) in solution. Selected reactions were followed by NMR and the kinetic constants calculated. A mechanism is proposed based on the equations used for the calculations.
