A series of iron(III) 1-D polymeric materials of the general formula [Fe(III)(Schiff-base)(L)](BPh(4)).n(CH(3)OH) (Schiff base = N,N'-ethylenebis(salicylaldimine) (H(2)salen), N,N'-o-phenylenebis(salicylaldimine) (H(2)salophen) and N,N'-ethylenebis(acety1acetone)-2,2'-imine (H(2) acen); L = bridging di-pyridyl or di-imidazole ligand, n = 0-4) and analogues therein, have been synthesised and str...

In the title compound, C(15)H(13)NO(4), the dihedral angle between the substituted benzene rings is 9.9 (8)°. Part of the mol-ecule (the salicylaldimine segment) is disordered over two sets of sites, with a refined site-occupancy ratio of 0.550 (14):0.450 (14). Intra-molecular O-H⋯N hydrogen bonds form S(6) ring motifs. In the crystal, pairs of O-H⋯O hydrogen bonds link mol-ecules into centrosy...

The monomeric title nickel(II) complex of a salicylaldimine, [Ni(C(20)H(14)N(2)O(4))]·2CH(3)OH, was obtained by the reaction of 2,4-dihydroxy-benzaldehyde and 1,2-phenyl-enediamine with nickel(II) acetate. The Ni(II) atom is coordinated by two N atoms [Ni-N = 1.839 (2) Å] and two O atoms [Ni-O = 1.8253 (19) Å] in an approximately square-planar geometry. In the crystal structure, inter-molecular...

Zinc(II) complexes with dangling functional organic groups were synthesized by reaction of zinc acetate with a series of bifunctional p-substituted benzene derivatives (a combination of carboxylate, oximate, amino, β-ketoimine, and salicylaldime groups). Selective coordination to carboxylate groups was observed when the second functional group was an oxime or β-ketoimine group. When the second ...

The title compound, [Fe(C(16)H(11)N(2)O)(2)]N(3), consists of a [Fe(qsal)(2)](+) cation [Hqsal = N-(8-quinol-yl)salicylaldimine] and an azide anion. The Fe(III) ion, lying on a twofold rotation axis, is coordinated by four N atoms and two O atoms from two tridentate qsal ligands in an octa-hedral geometry. The mol-ecules are connected into a three-dimensional network by inter-molecular C-H⋯N an...
