Poly[[diaquadi-?(2)-cyanido-bis-(?(2)-pyrazine-2-carboxyl-ato)dicopper(I)copper(II)] dihydrate].

ABSTRACT: In the title compound, {[Cu(II)Cu(I) (2)(C(5)H(3)N(2)O(2))(2)(CN)(2)(H(2)O)(2)]·2H(2)O}(n), the Cu(II) atom lies on an inversion centre and is octa-hedrally coordinated by two N atoms and two O atoms from opposing pyrazine-2-carboxyl-ate (2-pac) ligands and two water O atoms. The Cu(I) atom has a triangular geometry, coordinated by one N atom and one C atom from two bridging cyanide ligands, and another N atom from the 2-pac ligand. The three-dimensional structure features a succession of two-dimensional sheets containing [Cu(CN)](n) chains linked by Cu(2-pac)(2)(H(2)O)(2) groups. The coordinated and free water mol-ecules are involved in an extended three-dimensional hydrogen-bond network with the 2-pac ligands.

Project description:The title six-coordinated distorted octa-hedral complex, [Cu(C(6)H(3)N(2)O(4))(2)(C(10)H(8)N(2))]·2H(2)O, consists of two 3-carboxy-pyrazine-2-carboxyl-ate anions and one 2,2'-bipyridine ligand. There is a twofold rotation axis positioned at the Cu(II) center.

The inter-actions existing in the crystal structure are inter-molecular O-H⋯O hydrogen bonds, and C-H⋯O and C-O⋯π inter-actions (O⋯π =3.145 Å, C-O⋯π = 149.75°).

Project description:In the polymeric complex of the title compound, {[AgNi(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)]NO(3)·2H(2)O}(n), the Ag(I) ion displays an angular coordination geometry with two N atoms from pyrazine-2-carboxyl-ate ligands, and the Ni(II) ion is hexa-coordinated by two O atoms from two water mol-ecules, two O and two N atoms from pyrazine-2-carboxyl-ate ligands in a distorted octa-hedral geometry. In the crystal, the Ag(I) and Ni(II) ions lie on a mirror plane and an inversion centre, respectively. The complex chains, the nitrate ions and the uncoordinated water mol-ecules are linked together through O-H?O hydrogen bonds and weak Ag?O inter-actions [2.619?(17)-2.749?(17)?Å] into a three-dimensional network.

Project description:In the title compound, {[Cu(C(6)H(5)N(2)O(2))(2)]·2H(2)O}(n), the Cu(II) ion (site symmetry ) is coordinated by two N,O-bidentate ligands and two N-monodentate ligands in a distorted CuO(2)N(4) octa-hedral geometry.

Project description:In the title complex, [Co(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O, the coordination geometry of the Co(2+) cation is distorted octa-hedral, with two N atoms and two O atoms from two 5-methyl-pyrazine-2-carboxyl-ate ligands in the equatorial plane. The two remaining coordination sites are occupied by two water mol-ecules. In addition, there are two uncoordinated water mol-ecules in the asymmetric unit. The crystal structure is stabilized by a network of O-H?O and O-H?N hydrogen-bonding inter-actions, forming a three-dimensional structure.

Project description:The title compound, {[Cu(C(17)H(11)N(2)O(3))(2)(H(2)O)]·2H(2)O}(n), is a two-dimensional polymer. The Cu(2+) ion lies on the crystallographic twofold axis.

All of the H atoms in the amide group and lattice water mol-ecules participate in O-H?O or N-H?O hydrogen bonding to strengthen the two-dimensioal framework of the polymer.

Poly[[hepta-?(2)-aqua-bis-(?(2)-pyrazine-2-carboxyl-ato)dibarium] bis-(pyrazine-2-carboxyl-ate)].

Project description:In the layered title coordination polymer, {[Ba(2)(C(5)H(3)N(2)O(2))(2)(H(2)O)(7)](C(5)H(3)N(2)O(2))(2)}(n), the coordination geometries around the two independent Ba(II) ions can be described as bicapped square-anti-prismatic [BaNO(9)] arrangements. A two-dimensional polymeric framework with (6,3) topology can be observed in the ac plane, the nodes being provided by Ba(II) ions and the connectors being N and O atoms belonging to pyrazine-2-carboxyl-ate ligands and O atoms of bridging water mol-ecules. Non-coordinating pyrazine-2-carboxyl-ate ions are located between the polymeric layers in the crystal and are interconnected through extensive O-H?N,O hydrogen bonding.

Poly[aqua-(?-pyrazine-2-carboxyl-ato-?N,O:O)(?-pyrazine-2-carboxyl-ato-?N,O:O')lead(II)].

Project description:The polymeric structure of the title compound, [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](n), is built up from centrosymmetric [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](2) dimers, which are bridged by ligand carboxyl-ate O atoms. The Pb(II) ion adopts an irregular PbN(2)O(5) coordination polyhedron; it is chelated by one N,O-bidentate ligand and also bonds to a water O atom. A second N,O-bidentate ligand forms the dimer bridge and another bridging O atom from a nearby dimer also bonds to the Pb(II) ion, leading to layers propagating in (100). A network of O-H?O hydrogen bonds operates between water O atoms (donors) and carboxyl-ate O atoms (acceptors).

Disorder in the anionic part of catena-poly[[(pyrazine-2-carboxyl-ato)copper(II)]-?-pyrazine-2-carboxyl-ato].

Project description:The title compound, [Cu(C(5)H(3)N(2)O(2))(0.88)(C(6)H(4)NO(2))(1.12)](n), is characterized by disorder of the anion, resulting from a statistical occupation in a 0.44?(3):0.56?(3) ratio of pyrazine-2-carboxylate and pyridine-2-carboxylate. The compound was isolated during attempts to synthesize a mixed-ligand coordination polymer by solvothermal reaction between copper(II) nitrate and equimolar mixtures of pyrazine-2-carboxylic acid and pyridine-2-carb-oxy-lic acid in a mixture of water and EtOH. The difference in the two components of the compound is due to substitutional disorder of a CH group for one of the N atoms of the pyrazine ring which share the same site in the structure. In the crystal structure, the Cu(II) atom lies on an inversion centre and is six-coordinated in a distorted N(2)O(4) geometry. The carboxyl-ate group carbonyl O atoms are weakly coordinated to an equivalent Cu(II) atom that is translated one unit cell in the a-axis direction, thus forming a polymeric chain through carboxyl-ate bridges.
