“…Both of the copper atoms are coordinated by a four carboxylato oxygen atoms of caproxy -and pyridyl nitrogen atom of pds with Cu-O distances of 1.932(6)-1.970(5) Å and Cu-N distances of 2.144(6) and 2.165(6) Å, respectively, to form a distorted square pyramidal geometry. This feature is originated from the Jahn-Teller distortion of copper(II) ion and has been similarly observed in several related chain compounds of copper(II) carboxylate groups [10,12,19,21,22]. The copper atom lies on the basal O 4 plane toward the axial nitrogen atom by 0.20 Å for Cu1 and Cu2.…”

Previously, we reported that a chain compound of copper(II) benzoate with pyrazine shows an adsorption property for N 2 because of the hydrophobic micropore that is formed by the aromatic benzoate groups [12,24].…”

Chain compounds of paddle-wheel Cu 2 -clusters of 3-carboxy-2,2,5,5-tetramethyl-1-pyrrolidinyloxy (Hcaproxy) and 4-carboxy-2,2,6,6-tetramethylpiperidinyloxy (Hcatempo) and N,N'-bidentate ligands (L = 4,4 -bipyridine (4,4 -bpy), 1,2-bis(4-pyridyl)ethane (bpe), trans-1,2-bis(4-pyridyl)ethylene (bpel), 4,4 -dipyridyl disulfide (pds), 1,4-diazabicyclo[2.2.2]octane (dabco), and pyrazine (pyz)), [Cu 2 (caproxy) 4 (L)] n , and [Cu 2 (catempo) 4 (L)] n , were synthesized and characterized by elemental analysis, infrared and UV-vis spectra and temperature dependence of magnetic susceptibilities (4.5-300 K). The crystal structures of [Cu 2 (caproxy) 4 (pds)] n , [Cu 2 (catempo) 4 (4,4 -bpy)] n , and [Cu 2 (catempo) 4 (bpe)] n revealed zigzag or linear chains consisting of alternate arrangement of the dinuclear cluster bearing four nitroxide radicals and N,N'-bidentate ligand. Temperature dependence of magnetic susceptibilities showed a considerable antiferromagnetic interaction between the two copper(II) ions within the dinuclear cluster, and weak antiferromagnetic interaction between the dinuclear clusters and/or the radical and dinuclear cluster.

“…The dinuclear unit has a lantern-like dinuclear core bridged by four 345tmbzligands in a syn-syn fashion [Mikuriya, 2008]. The Cu1•••Cu1 i distance is 2.6190(6) Å, which is in the range found in dinuclear copper(II) carboxylates [Mikuriya, 2008;Mikuriya et al, 1995;Mikuriya et al, 2015a;Mikuriya et al, 2015b;Nukada et al, 1999].

“…Copper acetate [Cu2(CH3CO2)4(H2O)2] is a famous copper(II) compound with a lantern-like dinuclear core and has attracted much attention for a long period because of the unique structure and properties [Horikoshi and Mikuriya, 2005;Matsushima et al, 1999;Mori et al, 1999;Mikuriya et al, 1995;Mikuriya et al, 1977;Mikuriya et al, 2000a;Mikuriya et al, 2000b;Mikuriya et al, 2002a;Mikuriya et al, 2002b;Mikuriya, 2008;Mikuriya et al, 2015a;Mikuriya et al, 2015b, Nakashima et al, 1985Nukada et al, 1999;Nukada et al, 2001;Nukada et al, 2015].

Copper(II) 3 ,4, [Cu2(3,4,5-(CH3O)3C6H2CO2)4 (CH3OH)2]·2DMF, was prepared and characterized by elemental analysis, infrared and UV-vis spectra and temperature dependence of magnetic susceptibilities (4.5-300 K). The crystal structure was determined by the single-crystal X-ray diffraction method. It crystallizes in the triclinic space group P 1 _ with a = 8.2110 (13) Å, b = 13.181(2) Å, c = 13.409(2) Å, α = 97.967(3)°, β = 102.378(3)°, γ = 105.009(3)°, V = 1339.8(4) Å 3 , Dx = 1.465 g/cm 3 , and Z = 1. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0363 and 0.0816, respectively, for all 5991 independent reflections. The crystal contains crystallographically centrosymmetric dinuclear molecule with axial methanol molecules and crystal DMF molecules [Cu···Cu 2.6190(6) Å]. Magnetic susceptibility data show a considerable antiferromagnetic interaction between the two copper(II) ions (2J = -292 cm -1 ). Gas-adsorption behavior was investigated for N2.

“…Dinuclear metal carboxylates have attracted considerable attention due to their potential application for functional materials, such as gas storage, [1][2][3][4] as well as their unique structures and magnetic properties. [5][6][7][8][9][10][11][12] Recently, we reported on the dinuclear copper(II) carboxylate obtained from the reaction of 3,4,5-trimethoxybenzoic acid (H345-tmbz) and copper(II) salt, [Cu2(345-tmbz)4(CH3OH)2]•2dmf (1), which has a syn-synbridged dinuclear cluster with a Cu-Cu distance of 2.6190(6)Å. 11 We also synthesized the dinuclear cluster [Cu2(tbng)4(dmf )2] (tbng -= 3,4,5-tri-O-benzylgallate) (2).…”
