Poly[tetra-kis(?(4)-4,6-dimethyl-5-nitro-benzene-1,3-dicarboxyl-ato-?O:O:O:O)bis-(pyridine-?N)dizinc].

ABSTRACT: In the title complex, [Zn(2)(C(10)H(7)NO(6))(2)(C(5)H(5)N)(2)](n), the repeat unit is a centrosymmetic tetra-carboxyl-ato-O,O'-bridged dimer in which each Zn(II) atom is five-coordinated by four O atoms from different dianionic 4,6-dimethyl-5-nitro-iso-phthalate ligands [Zn-O = 2.0283?(18)-2.0540?(19)?Å] and one N atom from a pyridine mol-ecule [Zn-N = 2.030?(2)?Å] in the axial site of a slightly distorted square-pyramidal coordination sphere. The Zn?Zn separation is 2.9750?(6)?Å. The complex dimers are extended into a two-dimensional polymeric structure parallel to (100) through bridges provided by the second carboxyl-ate group of the ligand.

Project description:In the mononuclear title complex, [Cd(C(8)H(4)O(4))(C(8)H(7)N(3))(2)(H(2)O)], the Cd(II) atom is six-coordinated in a distorted octa-hedral geometry by four N atoms from two bidentate chelating 2-(1H-pyrazol-3-yl)pyridine ligands, one O atom from a benzene-1,2-dicarboxyl-ate ligand and one water mol-ecule.

Project description:The title compound, {(C(10)H(10)N(2))[Ce(2)(C(7)H(3)NO(4))(4)(H(2)O)(4)]·5H(2)O}(n), is composed of a one-dimensional anionic complex, a doubly protonated 4,4'-bipyridine mol-ecule as a counter-ion and five uncoordinated water mol-ecules. The anion bears two nine-coordinate Ce(III) ions, each with a distorted tricapped trigonal-prismatic geometry. In the crystal, inter-molecular C-H⋯O, N-H⋯O and O-H⋯O hydrogen bonds, as well as π-π inter-actions with centroid-centroid distances of 3.514 (3) Å connect the various components into a supra-molecular structure.

Project description:In the title compound, [Cu(C(7)H(3)NO(4))(C(6)H(6)N(2)O)(H(2)O)], the coordination geometry of the Cu(II) atom can be described as distorted square pyramidal. The basal plane is defined by one N atom and two O atoms from the deprotonated pyridine-2,6-dicarboxyl-ate ligand, and a pyridyl N atom from the 4-pyridyl aldoxime ligand. The apical position is occupied by a water mol-ecule. O-H⋯O hydrogen bonds lead to the formation of a two-dimensional network.

Project description:The title compound, [Tm(4)(C(8)H(4)O(4))(6)(H(2)O)(2)](n), has been synthesized hydro-thermally.

Adjacent sheets are further packed to form a three-dimensional supra-molecular framework through O-H?O hydrogen bonds.

Project description:The reaction of Co(NO(3))(2)·3H(2)O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C(7)H(3)NO(4))(C(5)H(8)N(2))(3)]·H(2)O. The Co(II) atom is coordinated by one pyridine-2,6-dicarboxyl-ate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octa-hedral geometry. Hydrogen-bonding interactions involving the coordinated carboxylate group, 3,5-dimethyl-1H-pyrazole and water help to consolidate the crystal structure.

The dinuclear complex mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonding, forming a three-dimensional supra-molecular structure.
