چکیده
In the title dinuclear complex, (acetonitrile-1κN)[μ-N-(pyri-din-2-ylcarbonyl)pyridine-2-carboxamidato-1:2κ(5)N,N',N'':O,O'][N-(pyridin-2-ylcarbonyl)pyridine-2-carboxamidato-2κ(3)N,N',N'']bis(trifluoromethanesulfonato-1κO)dicopper(II), [Cu(2)(C(12)H(8)N(3)O(2))(2)(CF(3)O(3)S)(2)(CH(3)CN)], one of the Cu(II) ions is five-coordinated in a distorted square-pyramidal N(3)O(2) environment provided by two N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidate (bpca) ligands, while the second Cu(II) ion is six-coordinated in a distorted octa-hedral N(4)O(2) environment provided by one bpca ligand, two trifluoro-methansulfonate ligands and one acetonitrile mol-ecule. Weak inter-molecular C-H⋯O and C-H⋯F hydrogen bonds and π-π stacking inter-actions with centroid-centroid distances of 3.6799 (15) and 3.8520 (16) Å stabilize the crystal packing and lead to a three-dimensional network.

N,N′,N′′ versus N,N′,O imine-containing coordination motifs: ligand-directed synthesis of mononuclear and binuclear CuII compounds
It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N,N',N''-donating imine ligand led to a mononuclear compound, namely di-chlorido-[N,N-dimethyl-N'-(pyridin-2-yl-methyl-idene)ethane-1,2-di-amine]copper(II) monohydrate, [CuCl2(C10H15N3)]·H2O, 1, while the N,N',O-donating imine ligand produc...

The title compound, [CuCl2(C10H16N2O)], has been synthesized and characterized by synchrotron single-crystal X-ray diffraction and FT-IR spectroscopy. The 2-methyl-2-[(pyridin-2-ylmeth-yl)amino]-propan-1-ol (mpmapOH) ligand, including pyridine, amine and hy-droxy groups, was synthesized by the reaction of 2-amino-2-methyl-propan-1-ol with pyridine-2-carbaldehyde and was characterized by NMR spe...

The Mn(III) ion in the title complex, [Mn(C(15)H(10)N(3)O)(2)]ClO(4)·H(2)O, is coordinated meridionally by six N atoms from two tridentate N-(8-quinol-yl)pyridine-2-carboxamidate ligands, yielding a distorted octa-hedral coordination geometry. The two ligands are nearly planar and their mean planes are almost perpendicular, with a dihedral angle of 86.7 (2)°.

In the binuclear title compound, [Ag(2)(C(11)H(11)N(3))(2)](CF(3)O(3)S)(2), the complex cation is centrosymmetric, with the unique Ag(+) cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridin-2-ylmeth-yl)pyridin-2-amine ligands in a geometry slightly distorted from linear [N-Ag-N 161.02 (7)°]. This set-up leads to the formation of a 14-membered cyclic dimer. The two pyr...
