Catena-Poly[diacridinium [zinc(II)-di-?-pyrazine-2,3-dicarboxyl-ato-?N,O:O;O:N,O]].

ABSTRACT: The crystal structure of the title compound, {(C(13)H(10)N)(2)[Zn(C(6)H(2)N(2)O(4))(2)]}(n), consists of polymeric Zn complex anions and discrete acridinium cations. The Zn cation, located on an inversion center, is N,O-chelated by two pyrazine-2,3-dicarboxyl-ate (pyzdc) anions in the basal plane, and is further coordinated by two carboxyl-ate O atoms from adjacent pyzdc anions in the axial directions with a longer Zn-O bond distance, forming a distorted ZnN(2)O(4) coordination geometry. The pyzdc anions bridge the Zn cations, forming polymeric chains running along the crystallographic b axis. The acridinium cations are linked to the complex chains via N-H?O and C-H?O hydrogen bonding. Significant ?-? stacking between parallel acridinium ring systems is observed in the crystal structure, face-to-face distances being 3.311?(3) and 3.267?(4)?Å.

Project description:The Cu atom in the title complex, {[Cu(C(6)H(2)N(2)O(4))(H(2)O)(3)]·H(2)O}(n) or {[Cu(L)(H(2)O)(3)]·H(2)O}(n) (L is pyrazine-2,3-dicarbox-yl-ate), displays octa-hedral coordination formed by the ligand L and three coordinated water mol-ecules. The ligand L is tridentate, with one N atom of the pyrazine ring and one O atom of one carboxyl-ate group forming a chelate ring, whereas one O atom from the second carboxyl-ate group is coordinated to another Cu atom. The ligand L links mol-ecules to form an infinite chain parallel to the [101] direction. The chains are further linked through O-H⋯O and O-H⋯N hydrogen bonds involving the water mol-ecules to build up a three-dimensional network.

A new polymorph of catena-poly[[tri-aqua-cadmium(II)]-?(2)-pyrazine-2,3-dicarboxyl-ato].

Project description:The title complex, [Cd(C(6)H(2)N(2)O(4))(H(2)O)(3)](n), is a new monoclinic polymorph. The ortho-rhom-bic form has previously been reported [Ma et al. (2006 ?). Acta Cryst. E62, m2528-m2529]. The Cd-N and Cd-O bond lengths range from 2.265?(3) to 2.333?(3)?Å; a weak Cd-O inter-action is also present, the inter-atomic distance being 2.658?(4)?Å. The Cd(II) ions, which have a distorted penta-gonal-bipyramidal geometry, are bridged by pyrazine-2,3-dicarboxyl-ato ligands, forming a zigzag chain structure. The chains are connected by O-H?O hydrogen bonds into a three-dimensional framework.

Project description:In the title compound, [Co(C(6)H(2)N(2)O(4))(C(14)H(8)N(4))(H(2)O)](n), the Co atom is bonded to one N,N'-bidentate pyrazino[2,3-f][1,10]phenanthroline (Pyphen) ligand, one N,O-bidentate pyrazine-2,3-dicarboxyl-ate (PZDC) dianion and one water mol-ecule in a distorted octa-hedral mer-CoN(3)O(3) geometry. The Co(II) atoms are bridged by the PZDC dianions, forming an infinite one-dimensional chain running along the b axis. Adjacent chains pack together through ?-? stacking inter-actions [centroid-centroid separations = 3.498?(4) and 3.528?(4)?Å], and O-H?O and O-H?N hydrogen bonds involving the water mol-ecule complete the structure.

Project description:In the title compound, [Zn(C(6)H(2)N(2)O(4))(C(18)H(10)N(4))(H(2)O)](n) or [Zn(PZDC)(DPPZ)(H(2)O)](n) (where DPPZ is dipyrido[3,2-a:2',3'-c]phenazine and H(2)PZDC is pyrazine-2,3-dicarboxylic acid), the Zn atom is six-coordinated in a slightly distorted octa-hedral coordination geometry by three N atoms from one DPPZ ligand and one PZDC(2-) dianion, three O atoms from two different PZDC(2-) ligands and one water mol-ecule. Each PZDC(2-) dianion serves as a spacer, connecting adjacent metal atoms into a polymeric chain structure parallel to the b axis. The chain motif is consolidated into a three-dimensional supra-molecular network by O-H⋯O and O-H⋯N hydrogen bonds and π-π aromatic stacking inter-actions involving adjacent DPPZ ligands and PZDC(2-) dianions with centroid-centroid separations of 3.522 (6) and 3.732 (8) Å, respectively.

Project description:In the title polymer, [Mn(C(8)H(8)O(5))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa-hedral coordination mode, binding to the bridging O atom of the bicyclo-heptane unit, two O atoms from corresponding carboxyl-ate groups, one carboxyl-ate O atom from a symmetry-related bridging ligand and two water O atoms. This arrangement leads to the formation of polymeric chains propagating parallel to [001]. The crystal structure is stabilized by several O-H?O hydrogen-bonding inter-actions involving the coordinated water mol-ecules as donors and the carboxyl-ate O atoms as acceptors.

Adjacent Zn(II) cations are linked by a 1H-1,2,4-triazole-3,5-dicarboxyl-ate ligand in a μ(2),κ(3) fashion to form a chain running along the c axis. The crystal packing is stabilized by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds.

Project description:In the title compound, {[Cu(C(7)H(3)NO(4))(H(2)O)(3)]·H(2)O}(n), the Cu(II) ion is bonded to three water mol-ecules, one N,O-bidentate pyridine-2,3-dicarboxyl-ate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO(5) octa-hedral geometry.

catena-Poly[[triaqua-cadmium(II)]-μ-pyridine-2,3-dicarboxyl-ato-κN,O:O].

Project description:The title polymeric compound, [Cd(C(7)H(3)NO(4))(H(2)O)(3)](n) or [Cd(py-2,3-dc)(H(2)O)(3)](n), where py-2,3-dcH(2) is pyridine-2,3-dicarboxylic acid, was obtained by the reaction of cadmium(II) nitrate hexa-hydrate with (pipzH(2))(py-2,3-dc) as a proton-transfer compound in aqueous solution (pipz is piperazine). The mol-ecular structure shows that only the anionic fragment of the starting proton-transfer compound is present in the complex, while the (pipzH(2))(2+) dication has been lost. Each (py-2,3-dc)(2-) ligand bridges two Cd(II) atoms in two different coordination modes, i.e. one end acts as a monodentate and the other end as a bidentate ligand. The three remaining coordination sites on the metal center are occupied by water mol-ecules. The geometric arrangement of the six donor atoms around the Cd(II) atom is distorted octa-hedral. In the crystal structure, O-H⋯O and C-H⋯O hydrogen bonds play an important role in stabilizing the supra-molecular structure.
