چکیده

In the title compound, trans,trans-[μ-(m-phenyl-ene)bis-(ethyne-1,2-di-yl)]bis-[chlorido(1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)cobalt(III)]-trans,trans-[μ-(5-bromo-m-phenyl-ene)bis-(ethyne-1,2-di-yl)]bis-[chlorido(1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)cobalt(III)]-tetra-phenyl-borate-acetone (0.88/0.12/2/4), [Co(2)(C(12)H(4))Cl(2)(C(10)H(24)N(4))(2)](0.88)[Co(2)(C(10)H(3)Br)Cl(2)(C(10)H(24)N(4))(2)](0.12)(C(24)H(20)B)(2)·4C(3)H(6)O, with the exception of the acetyl-ene and bromine groups, all atomic postitions are the same in the two compounds and are modeled at full occupancy. The Co(III) ions are six-coordinate with acetyl-ide and chloride ligands bound to the axial sites and the N atoms from the cyclam rings coordinated at the equatorial positions. N-H⋯O and N-H⋯Cl hydrogen-bonding interactions help to consolidate the crystal packing.

Synthesis, Spectroscopy and Magnetic Characterization of Five Dinuclear Copper(II) Complexes with 2, 3 or 4-Pyridinemethanol as the Ligand

The synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(II) complexes are described. All five compounds have the general formula [Cu2(L)4(O-R)2](Cl)2 or [Cu2(L)2(Cl)2](Cl)2, in which R = CH3 or H, L=2, 3 or 4-pyridinemethanol as L2, L3 or L4, respectively. The title compounds consist of dinuclear units with bridging methoxo groups in [Cu2(L4)4(O-CH3)2](Cl)2, hydro...

Crystal structure of bis­{μ-1-[(E)-(3-meth­oxy­phen­yl)diazen­yl]naphthalen-2-olato-κ3 N 2,O:O}bis­({1-[(E)-(3-meth­oxy­phen­yl)diazen­yl]naphthalen-2-olato-κ2 N 2,O}copper(II))

The title dinuclear Cu(II) complex, [Cu2(C17H13N2O2)4], is located on an inversion centre. The Cu(II) atoms are each five-coordinated in a distorted square-pyramidal geometry by two N atoms and two O atoms from two bidentate ligands and one bridging O atom from another ligand. In the dinuclear complex, the Cu⋯Cu separation is 3.366 (3) Å. In the crystal, complex mol-ecules are linked via weak C...
