Catena-Poly[[bis-(nitrato-?O)copper(II)]-?-1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)-benzene-?N:N'].

ABSTRACT: In the title coordination polymer, [Cu(NO(3))(2)(C(12)H(12)N(2)O(2))](n), the Cu(II) ion, situated on an inversion center, is coordinated by two O atoms from two nitrate anions and two N atoms from two 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted square-planar geometry. Each L ligand also lies across an inversion center and bridges two Cu(II) ions, forming a polymeric chain running along the [101] direction. The three O atoms of the nitrate group are disordered over two positions in a 3:2 ratio.

2,6-Bis[(S)-4-benzyl-4,5-dihydro-1,3-oxazol-2-yl]pyridine.

Project description:The commercially available title compound, C(25)H(23)N(3)O(2), has been known since 1993 [Nesper et al. (1993 ?). Helv. Chim. Acta, 76, 2239-2249], but has not been structurally characterized until now. In the free ligand, the N atoms of both oxazoline rings point in opposite directions. The phenyl rings make dihedral angles of 30.56?(5) and 84.57?(3)° with the pyridine ring and 72.85?(3)° with each other.

Project description:The title tetra-nuclear Cu(II) complex, [Cu(4)(C(12)H(12)N(2)O(2))(4)(CH(3)O)(4)(ClO(4))(2)](ClO(4))(2), is located around an inversion center. Each Cu(II) atom is coordinated by two cis-O atoms from two bridging methano-late anions and two cis-N atoms from two bridging 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in the basal plane, and is further coordinated by one O atom of the bridging perchlorate anion, forming a distorted square-pyramidal geometry. The Cu?Cu separations in the recta-ngular core are 2.9878?(11) and 6.974?(1)?Å. In the asymmetric unit, there are two L ligands with a syn conformation. In one L ligand, the dihedral angles between the central benzene ring and the terminal 4,5-dihydro-1,3-oxazol-2-yl mean planes are 22.1?(4) and 33.1?(4)°, and in the other L ligand the corresponding dihedral angles are 29.3?(4) and 29.9?(4)°. The uncoordinated perchlorate anion is linked with the complex mol-ecules via weak C-H?O hydrogen bonds.

Project description:In the title compound, [Ag(3)(C(12)H(12)N(2)O(2))(4)](PF(6))(3), one Ag(I) ion, lying on a twofold rotation axis, is coordinated by four N atoms from four 1,3-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted tetra-hedral geometry and the other Ag(I) ion is coordinated by two N atoms from two L ligands in a bent arrangement [N-Ag-N = 169.03 (17)°]. Two L ligands adopt a syn conformation, while the other two adopt an anti conformation. They bridge adjacent Ag(I) ions, forming a trinuclear complex.
