Bis(quinolin-8-ol)silver(I) 2-hydroxy-3,5-dinitrobenzoate
The title compound, [Ag(C(9)H(7)NO)(2)](C(7)H(3)N(2)O(7)), was prepared from 3,5-dinitro-salicylic acid (DNS), quinolin-8-ol and AgNO(3). The Ag(I) atom is coordinated by two N atoms and two O atoms from two quinolin-8-ols in a roughly planar [maximum deviation = 0.223 (2) Å] environment. The two quinolin-8-ol ligands are bent slightly with respect to each other, making a dihedral angle of 9.55...

The title compound, [Ag(C9H6NO)(C9H7NO)], crystallizes as a non-centrosymmetric polymorph. The structure was previously reported by Wu et al. [(2006). Acta Cryst. E62, m281-m282] in the centrosymmetric space group Pbcn. The Ag(I) ion displays a distorted tetra-hedral coordination geometry defined by two N and two O atoms from a neutral quinolin-8-ol ligand (HQ) and a deprotonated quinolin-8-ola...

The reaction of 8-hy-droxy-quinoline, 2-methyl-quinolin-8-ol and stannic chloride yields the protonated 8-hy-droxy-2-methyl-quinolinium species. In the title salt, (C(10)H(10)NO)[Sn(C(9)H(6)NO)Cl(4)], the Sn(IV) cation is N,O-chelated by the quinolin-8-olate anion and is further coordinated by four Cl(-) anions in a distorted cis-SnNOCl(4) octa-hedral geometry. In the crystal, the cation is lin...

In the title compound, C20H20N2O2, the quinoline ring system makes dihedral angles of 81.05 (4) and 61.16 (5)° with the mean planes of the benzene and morpholine rings, respectively; the mean planes of the latter two rings make a dihedral angle of 83.59 (4)°. In the crystal, pairs of O-H⋯N hydrogen bonds link neighbouring mol-ecules related by a twofold rotation axis, generating R2(2)(10) motifs.

Condensation of 8-hy-droxy-quinoline-2-carbaldehyde with 2-amino-phenol gave the (E)-2-[(2-hy-droxy-phenyl-imino)-meth-yl]quinolin-8-ol derivative that reacted with di-n-butyl-tin oxide with release of H2O to yield the chelate title complex, [Sn2(C4H9)4(C16H10N2O2)2]. The compound crystallizes in the triclinic space group P-1, with two independent centrosymmetric dimers in the unit cell. Each f...
