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.

One of the two independent Mn atoms is seven-coordinate, binding to five carboxyl-ate O atoms from different chdc ligands and two phenanthrene N atoms from a dipyrido[3,2-a:2',3'-c]phenazine (L) ligand, while the second Mn atom is six-coordinate, binding to six carboxyl-ate O atoms from different chdc ligands. 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, [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, {[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.

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.

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.

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.

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 ?-? 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 ?-? inter-actions between the dipyridophenazine ligands [centroid-centroid distance = 3.506?(3)?Å], which lead to a one-dimensional supra-molecular structure.

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[?(2)-aqua-diaqua-(?(8)-3-nitro-benzene-1,2-dicarboxylato)(?(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 ?(8)- and ?(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[tris-(2,5-dimethyl-benzene-1,4--dicarboxyl-ato)bis-(pyridine)trizinc(II)].

Project description:The asymmetric unit of the title polymeric compound, [Zn(3)(C(10)H(8)O(4))(3)(C(5)H(5)N)(2)](n) or [Zn(3)(dmbdc)(3)(py)(2)](n) (dmbdc = 2,5-dimethyl-benzene-dicarboxyl-ate; py = pyridine) contains two Zn(II) ions, one of which is located on an inversion centre, one and a half 2,5-dimethyl-benzene-dicarboxyl-ate ligands and one pyridine ligand. Each ZnO(6) octa-hedron is sandwiched between two ZnO(4)N square-pyramids, forming a trinuclear zinc secondary building unit (SBU); each SBU is further linked by six 2,5-dimethyl-benzene-dicarboxyl-ate ligands with six adjacent trinuclear zinc SBU's, forming a two-dimensional layer structure with a (3,6) net. One of the three zinc ions is octa-hedrally coordinated and the other two are square-pyramidally coordinated. The coordination modes for 2,5-dimethyl-benzene-dicarboxyl-ates are bis-(bidentate) or bidentate-tridentate.
