catena-Poly[[[di-aqua-bis-[1,2-bis-(pyridin-4-yl)diazene]copper(II)]-μ-1,2-bis-(pyridin-4-yl)diazene] bis-(perchlorate)].

Project description:In the title compound, {[Cu(C10H8N4)3(H2O)2](ClO4)2} n , the coordination environment of the cationic Cu(II) atom is distorted octa-hedral, formed by pairs of symmetry-equivalent 1,2-bis-(pyridin-4-yl)diazene ligands, bridging 1,2-bis-(pyridin-4-yl)diazene ligands and two non-equivalent water mol-ecules. The 1,2-bis-(pyridin-4-yl)diazene mol-ecules form polymeric chains parallel to [-101] via azo bonds which are situated about inversion centres. Since the Cu(II) atom is situated on a twofold rotation axis, the monomeric unit has point symmetry 2. The perchlorate anions are disordered in a 0.536 (9):0.464 (9) ratio and are acceptors of water H atoms in medium-strong O-H⋯O hydrogen bonds with graph set R 4 (4)(12). The water mol-ecules, which are coordinated to the Cu(II) atom and are hydrogen-bonded to the perchlorate anions, form columns parallel to [010]. A π-π inter-action [centroid-centroid distance = 3.913 (2) Å] occurs between pyridine rings, and weak C-H⋯O inter-actions also occur.

3,5-Bis[(pyridin-4-yl)meth-oxy]benzoic acid.

Project description:Single crystals of the title compound, C19H16N2O4, were obtained under hydro-thermal conditions by an unintended recrystallization of the employed microcrystalline starting material. The [(pyridin-4-yl)meth-oxy]benzoic acid unit is nearly planar, with a maximum deviation from the least-squares plane of 0.194?(2)?Å. This plane is inclined by 35.82?(6)° to that defined by the second (pyridin-4-yl)meth-oxy group [in which the largest deviation from the least-squares plane is 0.013?(2)?Å]. In the crystal, mol-ecules are linked by O-H?N hydrogen bonds involving the acid hy-droxy group and a pyridine N atom into chains parallel to [-201].

Project description:In the title compound, C(15)H(15)N(5)O(4), a nitro-formazan derivative, the formazan unit is essentially planar with an r.m.s. deviation of 0.0204?(6)?Å and adopts a closed syn,s-cis configuration with an intra-molecular N-H?N hydrogen bond.

Project description:The Co(II) atom in the title salt, [Co(H(2)O)(6)](C(13)H(10)NO(3))(2)·2H(2)O, lies on a center of inversion in an octa-hedron of water mol-ecules. The cations, anions and uncoordinated water mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds into a three-dimensional network. The anion is essentially planar, with an r.m.s. deviation of all non-H atoms of 0.066 Å.

Project description:In the title compound, [Cd(NO(3))(2)(C(18)H(16)N(2)O(2))(2)](n), the six-coordinated Cd(II) ion is located on an inversion center and has a distorted octa-hedral environment defined by four N atoms from four 1,4-bis-(pyridin-3-ylmeth-oxy)benzene ligands and two O atoms from two nitrate anions.

One O atom of the nitrate anion is disordered over two positions with site-occupancy factors of 0.59?(2) and 0.41?(2).

(E)-1-(4-Meth-oxy-anthracen-1-yl)-2-phenyl-diazene.

Project description:The title compound, C(21)H(16)N(2)O, has an E-conformation about the diazene N=N bond. It is reasonably planar with the phenyl ring being inclined to the mean plane of the anthracene moiety [planar to within 0.077 (3) Å] by 6.43 (10)°. The crystal structure is stabilized by C-H⋯π and weak π-π inter-actions [centroid-centroid distances of 3.7192 (16) and 3.8382 (15) Å], leading to the formation of two-dimensional networks stacking along [001] and lying parallel to (110).

[1-Meth-oxy-3-(pyridin-2-yl)indolizin-2-yl](pyridin-2-yl)methanone.

Project description:Methyl-ation of [1-hy-droxy-3-(pyridin-2-yl)indolizin-2-yl](pyridin-2-yl)methanone was performed via metalation with potassium tert-butano-late in toluene and a subsequent metathesis reaction with methyl iodide yielded the yellow title compound, C(20)H(15)N(3)O(2). The substituents at the indolizine unit are twisted [the indolizine ring system makes dihedral angles of 34.67 (7) and 77.49 (5)°, respectively, with the pyridyl and pyridinoyl rings] with single bonds between the central unit and the attached pyridine ring [1.459 (3) Å] and the pyridinoyl group [1.483 (3) Å]. There are no classical hydrogen bonds in the crystal structure.

Project description:The title mol-ecule, C(17)H(14)F(3)NO(4), consists of two nearly planar fragments, viz. the 2-benzyl-oxypyridine (r.m.s. deviation 0.016?Å) and (E)-3-meth-oxy-prop2-enoic (r.m.s. deviation 0.004?Å) units, which form a dihedral angle of 84.19?(7)°. In the crystal, pairs of O-H?O hydrogen bonds link mol-ecules into dimers that are further connected by C-H?O and C-H?F inter-actions into (001) layers. In addition, ?-? stacking inter-actions are observed within a layer between the pyridine and benzene rings [centroid-centroid distance = 3.768?(2)?Å]. The F atoms of the trifluoro-methyl group are disordered over two sets of sites in a 0.53?(4):0.47?(4) ratio.

Project description:The asymmetric unit of the title compound, C(24)H(22)O(4), contains two independent mol-ecules in both of which the naphthalene ring systems adopts a transoid arrangement.
