Poly[diaqua-(?(3)-pyridine-3,5-dicarboxyl-ato-?N:O:O)copper(II)].

ABSTRACT: The title complex, [Cu(C(7)H(3)NO(4))(H(2)O)(2)](n), was prepared under hydro-thermal reaction conditions. In the crystal structure, the Cu(II) cation is located on a twofold rotation axis and is coordinated by two carboxyl-ate O atoms and one N atom from three pyridine-3,5-dicarboxyl-ate (PDA) anions and two water mol-ecules with a distorted trigonal-bipyramidal geometry. The tridentate PDA anion is also located on the twofold rotation axis and bridges the Cu(II) cations to form a two-dimensional polymeric layer. O-H?O hydrogen bonding between layers links the two-dimensional layers into a three-dimensional supra-molecular framework.

Project description:In the structure of the title compound, [Sr(C(7)H(3)NO(4))(H(2)O)(2)](n), the Sr(II) cation is eight-coordinated in form of a distorted dodeca-hedron by two water O atoms and by five O atoms and one N atom from five pyridine-3,5-dicarboxyl-ate anions. The bridging mode of the anions leads to the formation of a layered network parallel to (100). O-H?O hydrogen bonding between the coordinating water mol-ecules and the carboxyl-ate groups of adjacent layers consolidates the crystal packing. Weak C-H?O inter-actions are also observed.

Poly[triaqua-?(4)-pyridine-3,5-dicarboxyl-ato-barium(II)].

Project description:The reaction of the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) with Ba(NO(3))(2) leads to the formation of the title polymeric compound, [Ba(C(7)H(3)NO(4))(H(2)O)(3)](n). The Ba(II) atom is nine-coordinated by six carboxyl-ate O atoms from the (py-3,5-dc)(2-) ligands, and three O atoms from the coordinated water mol-ecules. The coordination polyhedron around the Ba(II) atom is best described as tricapped trigonal-prismatic. In the crystal structure, inter-molecular inter-actions, such as X-H?O hydrogen bonds (X = O and C) and ?-? stacking [centroid-centroid distances between pyridine rings of 3.6191?(13) and 3.6192?(13)?Å] play an important role in stabilizing the supramolecular structure.

Project description:In the crystal structure of the title compound, {[Fe(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)]·4H(2)O}(n), there are two types of coordination for the Fe(II) atoms. One Fe(II) atom is in a distorted octa-hedral N(2)O(4) environment, with two chelating rings from the pyridine-dicarboxyl-ate ligands and two O atoms from the water mol-ecules, while the other is in a distorted octa-hedral O(6) environment with two O atoms from the pyridine-dicarboxyl-ate ligands and four O atoms from the water mol-ecules. Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H?O hydrogen bonds.

Project description:The reaction of strontium(II) nitrate with the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (where pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) leads to the formation of the title polymeric compound, [Sr(C(7)H(3)NO(4))(H(2)O)(4)](n). The propane-1,3-diaminium cation is not incorporated in this crystal structure. The Sr(II) atom lies on an inversion centre and is eight-coordinated by four O atoms from three py-3,5-dc ligands and four O atoms from four coordinated water mol-ecules. The coordination polyhedron of the Sr(II) atom is a distorted dodeca-hedron. These binuclear units are connected via the carboxyl-ate O atoms to build a one-dimensional polymeric chain. In the crystal structure, non-covalant inter-actions consisting of hydrogen bonds (X-H?O, with X = O and C) and ?-? stacking inter-actions [3.4604?(19)?Å] connect the various components to form a supra-molecular structure.

Project description:The title mixed-metal complex, {(NH(4))(2)[Cu(C(7)H(3)NO(4))(2)(H(2)O)(2)][CdCu(C(7)H(3)NO(4))(2)(H(2)O)(6)]·6H(2)O}(n), contains one octa-hedrally coordinated Cd(II) center and two octa-hedrally coordinated Cu(II) centers, each lying on an inversion center. The two Cu(II) atoms are each coordinated by two O atoms and two N atoms from two 2,4-pydc (2,4-H(2)pydc = pyridine-2,4-dicarboxylic acid) ligands in the equatorial plane and two water mol-ecules at the axial sites, thus producing two crystallographically independent [Cu(2,4-pydc)(2)(H(2)O)(2)](2-) metalloligands. One metalloligand exists as a discrete anion and the other connects the Cd(H(2)O)(4) units, forming a neutral chain. O-H?O and N-H?O hydrogen bonds connects the polymeric chains, complex anions, ammonium cations and uncoordinated water mol-ecules into a three-dimensional supra-molecular network.
