Yi-Tao Li,Zhiguo Wang
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536807057455
Abstract: The title compound, C28H16N2O5, is a bis-imide derivative in which two phthalimide units are linked by an oxydi-p-phenylene bridge. The dihedral angle between the planes of the two central benzene rings is 86.1 (4)°. The isoindole groups make dihedral angles of 46.0 (14) and 77.5 (13)° with the attached benzene rings. Intermolecular C—H...O hydrogen bonds contribute to the stability of the structure.

Abstract: The dinucleic octaethylporphyrin (OEP) derivatives described as OEP-(p-Phen)n-OEP (n=1–4) were synthesized, in each of which the porphyrin ring is spaced with p-phenylene group. Their electronic properties were studied, as compared with those of the corresponding dihexylbithiophene (DHBTh) derivatives with head-to-head (HH) and tail-to-tail (TT) orientations. It proves that OEP-(p-Phen)n-OEP possesses an in-between feature of OEP-(HH-DHBTh)n-OEP and OEP-(TT-DHBTh)n-OEP in electronic properties.
N,N′-{[Bis(trifluoromethyl)methylene]di-p-phenylene}diphthalimide  [cached]
Yitao Li,Zhiguo Wang
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536807068249
Abstract: The molecule of the title compound, C31H16F6N2O4, consists of two phthalimide units linked by a [bis(trifluoromethyl)methylene]di-p-phenylene bridge, with the two halves of the molecule related to each other by a twofold rotation axis. The dihedral angle between the planes of the two central benzene rings is 70.5 (3)°. The terminal isoindole groups are approximately planar, with a maximum r.m.s. deviation of 0.006 from the mean plane, and they form dihedral angles of 46.03 (3)° to the attached benzene rings. Intermolecular C—H...O hydrogen bonds link neighboring molecules into chains along the c axis.
N,N′-(Methylenedi-p-phenylene)dibenzamide
Sohail Saeed,Naghmana Rashid,Rizwan Hussain,Peter G. Jones
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809031304
Abstract: The title compound, C27H22N2O2, consists of two chemically equivalent halves. However, it displays no crystallographic symmetry, only an approximate local twofold symmetry (r.m.s. deviation = 0.15 between the two halves of the molecule) is observed. In the crystal, molecules are connected by two antiparallel classical N—H...O hydrogen bonds, forming broad chains parallel to (10overline{1}). A series of weak C—H...N/O hydrogen bonds is also present.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809012513
Abstract: The title compound, C4H12N22+·2C2H2NO3 , contains a network of doubly protanated piperazinium cations (lying about centres of inversion) and dioxamate anions. The piperazinium dication adopts a typical chair conformation. The crystal structure is stabilized by cation–to–anion N—H...O and anion–to–anion N—H...O hydrogen bonds.

Abstract: The reaction of [RuCl(C9H10BN6)(C18H15P)2] with benzophenone imine in methanol, in the presence of sodium azide, leads to the formation of the title compound, [Ru(C9H10BN6)(N3)(HN=CPh2)(C18H15P)]·C4H10O, which crystallizes as the diethyl ether solvate. In the crystal structure, the Ru atom is coordinated by three N atoms of one hydridotris(pyrazoly)borate anion, one P atom of one triphenylphosphine ligand, one N atom of the azide anion and one N atom of the benzophenoneimine ligand in a slightly distorted octahedral geometry. The azide anion is almost linear [177.0 (5)°], with an Ru—N—N angle of 125.9 (3)°. There is a small difference between the N—N distances [1.200 (5) and 1.164 (5) ], the longer bond being adjacent to the Ru atom.
catena-Poly[[[tetraaquanickel(II)]-μ-4,4′-bipyridyl-κ2N:N′] 3,3′-(p-phenylene)diacrylate]
Ni-Ya Li
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811036993
Abstract: In the title compound, {[Ni(C10H8N2)(H2O)4](C12H8O4)}n, the NiII, 4,4′-bipyridyl (bipy) and 3,3′-(p-phenylene)diacrylate (L2 ) moieties are situated on inversion centres. The bipy ligands bridge NiII ions into positively charged polymeric chains along [101]. The NiII atom is coordinated by two N atoms from two bipy ligands and four water molecules in a distorted octahedral geometry. L2 anions interact with the polymeric chains via O–H...O hydrogen bonds, forming a three-dimensional supramolecular network.

Chinese Science Bulletin , 2003, DOI: 10.1007/BF03183244
Abstract: Poly(p-phenylene) (PPP) microtubules with diameters of 0.2–0.8 μm and lengths of ~10 μm have been synthesized by direct oxidation of benzene in the mixed electrolyte of boron trifluoride diethyl etherate (BFEE) and trifluoroacetic acid (TFA) (BFEE: TFA=2: 1, by volume), containing a certain amount of sodium dodecylbenzene-sulfonate (SDBS) as surfactant. The microtubules were grown vertically on the working electrode surface. The tubular morphology has been confirmed by scanning and transmission electron microscopies and the chain structure of the skin of the tubules has been characterized by Raman spectroscopy. The electrode property, monomer/surfactant molar ratio and the value of applied potential have strong effects on the morphology of the microtubules.

Abstract: Reaction of [Ru(Tp)Cl(PPh3)2] {where Tp is hydridotripyrazolylborate, BH[C3H3N2)3)]} with NH4[S2P(OEt)2] in methanol afforded the title compound, [Ru(C9H10BN6)(C4H10O2PS2)(C18H15P)], in which the RuII ion is in a slightly disorted octahedral coordination environment. The [S2P(OEt)2] ligand coordinates in a chelating mode with two similar Ru—S bond lengths and a slightly acute S—Ru—S angle. The atoms of both –OCH2CH3 groups of the diethyl dithiophosphate ligand are disordered over two sites with approximate occupancies of 0.76 and 0.24.
