Catena-Poly[potassium-di-?-aqua-?-4-(5-tetra-zolio)pyridine].

ABSTRACT: The title compound, [K(C(6)H(4)N(5))(H(2)O)(2)](n), was synthesized by hydro-thermal reaction of KOH with 4-(5-tetra-zolio)pyridine. The K atom has a distorted octa-hedral coordination environment and is coordinated by two axial N atoms from the organic ligand and by four water mol-ecules in the equatorial plane. The mol-ecules as a whole are located on crystallographic mirror planes; the K atom is also located on an inversion center. Both the water mol-ecules and the organic ligands act as bridges to link symmetrically the adjacent K atoms into polymeric chains parallel to the c axis. O-H?N hydrogen bonds involving the water O atoms and aromatic ?-? inter-actions [centroid-centroid distance 3.80?(2)?Å] between the pyridine and tetra-zole rings build up an infinite three-dimensional network.

Project description:In the title compound, {[La(C(6)H(4)NO(2))(2)(H(2)O)(4)]Cl}(n), the La(III) atom lies on a twofold rotation axis and is eight-coordinated by four O atoms from four isonicotinate ligands and four water mol-ecules in a distorted square-anti-prismatic coodination environment. Adjacent La(III) atoms are bridged by two carboxyl-ate groups from two isonicotinate ligands, forming an extended chain along [001]. These chains are linked through O-H?N hydrogen bonds into a three-dimensional network with channels in which the chloride anions form O-H?Cl hydrogen bonds. Intra-chain O-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance = 3.908?(2)?Å] are also observed.

Project description:The title polymeric compound, {[Cd(2)(C(7)H(3)NO(5))(2)(H(2)O)(4)]·4H(2)O}(n) or {[Cd(2)(hypydc)(2)(H(2)O)(4)]·4H(2)O}(n) (where hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of cadmium(II) nitrate hexa-hydrate with 4-hydroxy-pyridine-2,6-dicarboxylic acid and propane-1,3-diamine, in a 1:2:2 molar ratio in aqueous solution. The compound is a seven-coordinate binuclear polymeric complex with distorted penta-gonal bipyramidal geometry around Cd(II) [Cd-O = 2.247?(4)-2.474?(3)?Å]. In the binuclear monomeric units, the central atoms join together by O atoms of two bridging tridentate (hypydc)(2-) ligands, and the polymer propagates via two bridging water mol-ecules that link each Cd(II )centre of one monomer to the adjacent neighbour. Propane-1,3-diamine (pn) does not appear in the product but plays a role as a base. Inter-molecular O-H?O and C-H?O hydrogen bonds, and ?-? stacking inter-actions, with distances of 3.725?(3) and 3.766?(3)?Å, connect the various components.
