Poly[[diaqua-[?(4)-4,4'-carbonyl-bis(benzene-1,2-dicarboxyl-ato)]bis-(dipyrido[3,2-a:2',3'-c]phenazine)dicadmium(II)] monohydrate].

ABSTRACT: In the title compound, {[Cd(2)(C(17)H(6)O(9))(C(18)H(10)N(4))(2)(H(2)O)(2)]·H(2)O}(n), the Cd(II) atom is seven-coordinated by five O atoms from two different 4,4'-carbonyl-bis(benzene-1,2-dicarboxyl-ate) (BPTC) anions and one water mol-ecule, and by two N atoms from one chelating dipyrido[3,2-a:2',3'-c]phenazine (L) ligand in a distorted penta-gonal-bipyramidal geometry. The BPTC anions link the Cd(II) atoms, forming a one-dimensional chain structure. The L ligands are attached on both sides of the chain. A twofold rotation axis passes through the complex molecule. The crystal structure involves O-H?O hydrogen bonds.

Project description:In the title compound, [Co(C(14)H(8)O(4))(C(18)H(10)N(4))](n), the Co(II) atom is six-coordinated by four O atoms from two different biphenyl-2,2'-dicarboxyl-ate ligands and two N atoms from the bidentate dipyrido[3,2-a:2',3'-c]phenazine ligand in a distorted octa-hedral geometry.

Project description:In the title compound, [Fe(C(6)H(2)N(2)O(4))(C(18)H(10)N(4))(H(2)O)](n), the Fe(II) ion adopts a slightly distorted octahedral mer-FeN(3)O(3) geometry, arising from one N,N'-bidentate dipyrido[3,2-a:2',3'-c]phenazine ligand, one N,O-chelating pyrazine-2,3-dicarboxyl-ate dianion and one water mol-ecule. An O-bonded symmetry-related dianion completes the coordination of the metal. The bridging dianion results in a one-dimensional polymeric chain. Aromatic ?-? stacking inter-actions between ligands [centroid-centroid separations = 3.528?(2) and 3.741?(2)?Å] and O-H?O and O-H?N hydrogen bonds link the chains together, leading to a three-dimensional supra-molecular network.

Poly[diaqua-bis(2,2'-bipyridine)tris-(?(4)-2,2'-bipyridine-4,4'-dicarboxyl-ato)dineodymium(III)].

Project description:In the crystal structure of the title mixed-ligand coordination polymer, [Nd(2)(C(12)H(6)N(2)O(4))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)](n), the Nd(III) ion is in an octa-hedral coordination environment formed by one water mol-ecule, one chelating 2,2'-bipyridine ligand, and five monodentate carboxyl-ate groups. The local coordination polyhedron around the Nd(III) ion is a bicapped trigonal prism. Two Nd(III) centers are bridged by four carboxyl-ate groups to form an Nd(2) dimeric unit; these are further connected by 2,2'-bipyridine-4,4'-dicarboxyl-ate linkers, resulting in a layered coordination network.

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.

Poly[diaqua-?(4)-biphenyl-4,4'-dicarboxyl-ato-magnesium(II)].

Project description:The solvothermal reaction of magnesium nitrate with bi-phenyl-4,4'-dicarboxylic acid in N,N-dimethyl-formamide and water leads to the formation of crystals of the title complex, [Mg(C(14)H(8)O(4))(H(2)O)(2)](n).

The Mg cations are located on a center of inversion, the biphenyl-4,4'-dicarboxyl-ate anions around a twofold rotation axis and the water mol-ecule in a general position. The Mg cations are linked by the anions into a three-dimensional framework.

Furthermore, the chains are linked by O-H?O hydrogen bonds, forming a layer parallel to the ab plane.

Poly[tris-(μ-benzene-1,4-dicarboxylato)bis-(dipyrido[3,2-a:2',3'-c]phenazine)trimanganese(II)].

Project description:In the title compound, [Mn(3)(C(8)H(4)O(4))(3)(C(14)H(8)N(4))(2)](n), one Mn atom is located on an inversion centre and is six-coordinated by four carboxyl-ate O atoms from different benzene-1,4-dicarboxyl-ate (1,4-bdc) ligands and two phenanthrene N atoms from a dipyrido[3,2-a:2',3'-c]phenazine ligand. The other Mn atom is also six-coordinate, binding to six carboxyl-ate O atoms from different 1,4-bdc ligands. The dicarboxyl-ate groups chelate and bridge the two Mn atoms and a symmetry-related Mn atom to form a trimanganese unit. Bridging of the trinuclear Mn(II) clusters leads to a two-dimensional structure.

Dichlorido(dipyrido[3,2-a:2',3'-c]phenazine)manganese(II).

Project description:The complete mol-ecule of the title compound, [MnCl(2)(C(18)H(10)N(4))(2)], is generated by crystallographic twofold symmetry with the Mn atom lying on the rotation axis. The Mn coordination geometry is a distorted cis-MnCl(2)N(4) octa-hedron, arising from two N,N'-bidentate dipyrido[3,2-a:2',3'-c]phenazine (DPPZ) ligands and two chloride ions. In the crystal structure, neighbouring mononuclear units pack together through ?-? contacts between the DPPZ rings [shortest centroid-centroid distance = 3.480?(2)?Å], leading to a chain-like structure along [001]. C-H?Cl hydrogen bonds complete the structure.
