RESUMO
In the title compound, [Cd(C(8)H(4)O(5))(C(12)H(12)N(2))], the Cd(II) cation is coordinated by three 5-hy-droxy-isophthalate anions and one 5,5'-bimethyl-2,2'-bipyridine ligand in a distorted CdO(4)N(2) octa-hedral geometry. The 5-hy-droxy-isophthalate anions bridge the Cd cations, forming a two-dimensional polymeric complex parallel to (100). In the complex, the hy-droxy group is linked to the uncoordinated carb-oxy-O atom via an O-Hâ¯O hydrogen bond. Weak C-Hâ¯O hydrogen bonds are also present in the crystal structure. One of the methyl groups is disordered over two positions in a 0.536â (11):0.464â (11) ratio.
RESUMO
A novel metal-organic framework based on 1,3-bis-(imidazol-1-ylmeth-yl)benzene (1,3-bimb), [Cd(NO(3))(2)(C(14)H(14)N(4))(2)](n), has been synthesized hydro-thermally. The structure exhibits a two-dimensional metal-organic (4,4)-net composed of Cd(II) atoms and bimb ligands, and such layers are further joined through inter-layer C-Hâ¯O hydrogen bonds to generate a three-dimensional supra-molecular structure.
RESUMO
The crystal structure of the title compound, (C(16)H(13)FN)[Ni(C(3)S(5))(2)], consists of Ni(III) complex anions and 1-(2-fluoro-benz-yl)quinolinium (fbq) cations. In the complex anion, the Ni(III) cation is chelated by two 2-sulfanylidene-1,3-dithiole-4,5-dithiol-ate (dmit) dianions in a distorted square-planar geometry; the two dmit mean planes are twisted with respect to each other at a dihedral angle of 8.44â (3)°. In the fbq cation, the dihedral angle between the benzene ring and the quinoline ring system is 80.57â (14)°. The centroid-centroid distance of 3.860â (5)â Å between benzene rings indicates π-π stacking between adjacent fbq cations. The distance of 3.4958â (18)â Å between the S atom and the centroid of the pyridine ring suggests the existence of a lone-pair-aromatic inter-action between the anion and the cation. A short Sâ¯S contact [3.387â (2)â Å] is also observed in the crystal structure.
