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

ABSTRACT: 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.

The cis-chdc ligands bridge the trinuclear Mn(II) clusters, forming chains, which are further linked into a three-dimensional network.

Project description: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. The Co(II) atoms are bridged by the biphenyl-2,2'-dicarboxyl-ate ligands to form a one-dimensional chain structure. π-π inter-actions between neighbouring chains result in a two-dimensional supra-molecular network (centroid-to-centroid separation = 3.381 Å).

Poly[μ(2)-aqua-diaqua-(μ(8)-3-nitro-benzene-1,2-dicarboxylato)(μ(6)-3-nitro-benzene-1,2-dicarboxylato)tetra-sodium].

Project description:In the title layered coordination polymer, [Na(4)(C(8)H(3)NO(6))(2)(H(2)O)(3)](n), the doubly deprotonated 3-nitro-benzene-1,2-dicarboxyl-ate ligands exhibit μ(8)- and μ(6)-coordination modes to the sodium ions, generating sheets lying parallel to (001). The coordination environments of the sodium ions are distorted octa-hedral, distorted trigonal-bipyramidal and moncapped trigonal-prismatic. One of the nitro groups is disordered over two sets of sites with site-occupancy factors 0.580 (8):0.419 (2). A network of O-H⋯O and O-H⋯N hydrogen bonds helps to establish the packing.

Poly[bis-(μ(2)-3-carb-oxy-benzoato)bis-(dipyrido[3,2-a;2',3'-c]phenazine)bis-(μ(3)-isophthalato)tricopper(II)].

Project description:In the title compound, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(18)H(10)N(4))(2)](n), one Cu(II) atom, located on an inversion center, is hexa-coordinated and shows a distorted octa-hedral coordination geometry, while the other Cu(II) atom is penta-coordinated and exhibits a distorted square-pyramidal geometry. The Cu(II) atoms are bridged by isophthalate and 3-carb-oxy-benzoate ligands, forming a chain structure along the b axis. Furthermore, the chains are linked by O-H⋯O hydrogen bonds, forming a layer parallel to the ab plane.

Poly[[aqua-tris-(μ-benzene-1,4-dicarboxyl-ato)tricobalt(II)] methanol monosolvate monohydrate].

Project description:The asymmetric unit of the title compound, {[Co(3)(C(8)H(4)O(4))(3)(H(2)O)]·CH(3)OH·H(2)O}(n), consists of four crystallographically independent Co cations, four benzene-1,4-dicarboxyl-ate (bdc) anions, two water and one methanol solvent mol-ecule. Two of the Co cations and two of the bdc anions are located on centres of inversion, whereas all other atoms are located in general positions. In the crystal, two Co atoms are only fourfold coordinated by three O atoms from three bdc ligands and by one O atom from one coordinated water mol-ecule, while a third Co atom is coordinated by four O atoms from four bdc ligands within a strongly distorted tetra-hedral geometry. The other two Co cations are octa-hedrally coordinated by six O atoms from six bdc anions. The Co cations are linked by the bdc anions into a three-dimensional framework. From this arrangement, cavities are formed in which additional methanol and water mol-ecules are embedded.

catena-Poly[[aqua-(dipyrido[3,2-a:2',3'-c]phenazine-κN,N)zinc(II)]-μ-pyrazine-2,3-dicarboxyl-ato-κN,O:O].

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.

catena-Poly[[aqua-(dipyrido[3,2-a:2',3'-c]phenazine-κN,N)iron(II)]-μ-pyrazine-2,3-dicarboxyl-ato-κN,O:O].

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 π-π 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.

Project description:In the centrosymmetric dinuclear title compound, [Cu(2)(C(2)H(3)N)(2)(C(18)H(10)N(4))(2)(C(32)H(30)N(2)P(2))](BF(4))(2), the Cu(I) centre is coordinated by two N atoms from a dipyridophenazine ligand, one P atom from an N,N'-bis-[(diphenyl-phosphan-yl)meth-yl]benzene-1,4-diamine (bpbda) ligand, and one N atom from an acetonitrile mol-ecule in a distorted tetra-hedral geometry. The bpbda ligand, lying on an inversion center, bridges two Cu(I) centres into a Z-shaped complex. Intra-molecular π-π inter-actions between the dipyridophenazine ligand and the benzene ring of the bpbda ligand are observed [centroid-centroid distance = 3.459 (3) Å]. The crystal structure also involves inter-molecular π-π inter-actions between the dipyridophenazine ligands [centroid-centroid distance = 3.506 (3) Å], which lead to a one-dimensional supra-molecular 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 π-π 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.
