ABSTRACT: The asymmetric unit of the title compound, {[Cu(C(13)H(15)NO(3))(C(5)H(8)N(2))]·CH(3)OH}(n), contains two complex mol-ecules and two solvent mol-ecules. Each Cu(II) ion is in a distorted square-pyramidal coordination with one N and two O atoms from the Schiff base ligand and one N atom from the heterocycle in the basal positions and one carboxyl-ate O atom from a neighbouring ligand in the apical position. The apical Cu-O bonds are much longer than the basal Cu-O and Cu-N bonds. The carboxyl-ate groups of the Schiff base ligands bridge the Cu(II) ions, forming helical chains along [100]. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.Acta Crystallographica Section E Structure Reports Online 01/2011; 67(Pt 2):m173-4. · 0.35 Impact Factor -

ABSTRACT: In the title complex, [Cu(NCS)(2)(C(12)H(19)N(3))], the Cu(II) atom is five-coordinated in a square-pyramidal geometry defined by one pyridine N, one imine N, and one amine N atom of the tridentate Schiff base ligand and two N-bonded thio-cyanate ions (one of the latter occupying the apical site). The three bridging C atoms and the two terminal C atoms of the Schiff base are disordered over two sets of sites, with occupancies of 0.465 (2) and 0.535 (2).Acta Crystallographica Section E Structure Reports Online 01/2010; 66(Pt 10):m1274. · 0.35 Impact Factor -

ABSTRACT: In the title thio-cyanate-bridged polynuclear copper(II) complex, [Cu(C(10)H(12)NO(3))(NCS)](n), the Cu atom is five-coordinated in a square-pyramidal geometry, with one phenolato O, one imino N and one hy-droxy O atom of a Schiff base ligand and one thio-cyanato N atom defining the basal plane, and with one thio-cyanato S atom occupying the apical position. In the crystal structure, pairs of adjacent complex mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds into dimers. The dimers are further linked via Cu⋯S inter-actions, forming two-dimensional layers parallel to the bc plane.Acta Crystallographica Section E Structure Reports Online 01/2010; 66(Pt 9):m1172-3. · 0.35 Impact Factor -

ABSTRACT: The asymmetric unit of the title complex, [Ni(NCS)(2)(C(13)H(20)N(2)O(2))(2)], consists of two half-mol-ecules, both of which are completed by crystallographic inversion symmetry (Ni(2+) site symmetry = in both cases). Both metal ions are six-coordinated in distorted trans-NiO(2)N(4) geometries arising from two N,O-bidentate Schiff base ligands and two N-bonded thio-cyanate ions. The mol-ecular conformations are reinforced by two intra-molecular N-H⋯O hydrogen bonds.Acta Crystallographica Section E Structure Reports Online 01/2010; 66(Pt 11):m1352. · 0.35 Impact Factor -

ABSTRACT: In the title compound, [Cu(C(15)H(11)N(3)O(3))(C(10)H(8)N(2))], the Cu(II) atom is five-coordinated in a distorted square-pyramidal CuN(3)O(2) geometry. The basal positions are occupied by three donor atoms from the tridentate Schiff base ligand and by one N atom from the 2,2'-bipyridine ligand. The axial position is occupied by the other N atom of the 2,2'-bipyridine ligand. The crystal structure is consolidated by weak C-H⋯O hydrogen bonds. In addition, π-π inter-actions between adjacent pyridine rings (centroid-centroid distances = 3.238 and 3.313 Å) may also stabilize the crystal packing.Acta Crystallographica Section E Structure Reports Online 01/2009; 65(Pt 10):m1212-3. · 0.35 Impact Factor -

ABSTRACT: In the title compound, C(22)H(16)N(2)OS(2), the phenanthrene ring is nearly perpendicular to the phenyl ring, making a dihedral angle of 87.2 (2)°. Intra-molecular N-H⋯O inter-actions are present. In the crystal structure, the mol-ecules are linked through inter-molecular C-H⋯O inter-actions. The crystal structure is also stabilized by C-H⋯π inter-actions and weak π-π contacts [centroid-centroid distance = 3.36 (6) Å].Acta Crystallographica Section E Structure Reports Online 01/2009; 65(Pt 11):o2853. · 0.35 Impact Factor -

ABSTRACT: In the title compound, [Cu(C(11)H(11)NO(4))(H(2)O)]·H(2)O, each Cu(II) ion is four-coordinated by one N and two O atoms from the tridentate Schiff base ligand, and by one O atom from the coordinated water mol-ecule in a distorted square-planar geometry.

ABSTRACT: The mol-ecule of the title compound, C(14)H(10)BrClN(2)O(3), is planar [dihedral angle between the aromatic rings = 3.0 (2)°] and shows a trans configuration with respect to the C=N double bond.
