N,N'-Di-8-quinolyl-2,2'-(o-phenyl-ene-di-oxy)diacetamide.

ABSTRACT: In the title compound, C(28)H(22)N(4)O(4), the mol-ecule lies on a crystallographic twofold axis. The quinoline ring is essentially planar (give max or rms deviation 0.0186?Å), and the dihedral angle between the quinoline ring and the central benzene ring is 19.1?(4)°. Intra-molecular N-H?(N,O) and C-H?O hydrogen bonds contribute to the formation of the roughly planar configuration. The crystal packing is stabilized by inter-molecular C-H?O hydrogen bonds, and weak ?-? inter-actions between the pyridine rings and central benzene rings of the neighboring mol-ecules [centroid-centroid separation = 3.9009?(6)?Å].

2,2'-Diazinodimethylidyne)di-o-phenyl-ene) dibenzoate.

Project description:The title compound, C(28)H(20)N(2)O(4), was synthesized by the reaction of 2-(hydrazonometh-yl)phenyl benzoate with iodine. The mol-ecule possesses a crystallographically imposed center of symmetry at the mid-point of the hydrazine N-N bond. The substituents at the ends of the C=N bonds adopt an E,E configuration. Inter-molecular C-H⋯π(arene) hydrogen bonds and aromatic π-π stacking inter-actions [centroid-centroid distance 3.900 (1) Å] link the mol-ecules into (100) sheets. In addition, there is an inter-molecular C-H⋯O hydrogen-bond inter-action.

Poly[[tetra-aqua-bis[?(4)-2,2'-(p-phenyl-ene-di-oxy)diacetato][?(2)-2,2'-(p-phenyl-ene-di-oxy)diacetato]dierbium(III)] hexa-hydrate].

Project description:The asymmetric unit of the title compound, [Er(2)(C(10)H(8)O(6))(3)(H(2)O)(4)]·6H(2)O, comprises one Er(3+) ion, one and a half 2,2'-(p-phenyl-enedi-oxy)diacetate (hqda) ligands, two coordinated water mol-ecules and three uncoordinated water mol-ecules. The Er(3+) ion is nine-coordinated by seven O atoms from hqda ligands and two O atoms from water mol-ecules. In the title compound, there are two types of crystallographically independent ligands: one with an inversion center in the middle of the ligand is chelating on both ends of the ligand towards each one Er center; the other hqda ligands are bridging-chelating on one side, and bridging on the other end of the ligand. Two adjacent Er(3+) ions are thus chelated and bridged by -COO groups from hqda ligands in three coordination modes (briding-chelating, bridging and chelating). These building blocks are linked by OOC-CH(2)O-C(6)H(4)-OCH(2)-COO spacers, forming two-dimensional neutral layers. Adjacent layers are linked by O-H?O hydrogen-bonding inter-actions, forming a three-dimensional supermolecular network.

Propane-2,2-diyl di-p-phenyl-ene dibenzoate.

Project description:The V-shaped propeller-like mol-ecule of the title compound, C(29)H(24)O(4), does not exhibit crystallographic twofold symmetry as the two benzene rings are twisted asymmetrically with respect to both the central propyl plane and the benzo-yloxy groups [4.6 (2), 43.6 (2)° and 45.07 (8), 69.50 (8)°]. In the crystal structure, centrosymmetrically related mol-ecules form a dimer through C-H⋯π inter-molecular inter-actions.

1,1'-{2,2'-[1,4-Phenyl-enebis(methyl-ene)]bis-(-oxy)bis-(2,1-phenyl-ene)}diethanone.

Project description:The asymmetric unit of the title compound, C(24)H(22)O(4), contains one half-mol-ecule, the other half being generated by a crystallographic center of inversion. The central benzene ring makes a dihedral angle of 72.49 (5)° with the terminal benzene ring. In the crystal, adjacent mol-ecules are linked through C-H⋯O inter-actions, forming a sheet structure parallel to the bc plane. The sheets are stacked along the a axis via π-π inter-actions formed between the terminal benzene rings [centroid-centroid separation = 3.7276 (6) Å].

2,2'-Diamino-N,N'-(o-phenyl-ene)di-benz-amide.

Project description:In the structure of the title compound, C(20)H(18)N(4)O(2), the N-H and C=O bonds are trans to each other and the amide O atoms are syn to the ortho amino N atom in the benzoyl rings. The amide groups form dihedral angles of 8.4 (2) and 13.8 (2)° with their respective benzoyl rings, and dihedral angles of 51.85 (16) and 51.19 (17)° with the phenyl-enediamine ring. In the crystal, a centrosymmetric dimer is formed by inter-molecular N-H⋯O hydrogen bonds, resulting in an R(2) (2)(14) descriptor on a unitary level of graph-set analysis, and three intramolecular N-H⋯O bonds also occur.

Di-tert-butyl 2,2'-[9H-fluorene-9,9-diylbis(p-phenyl-ene-oxy)]diacetate.

Project description:In the title mol-ecule, C(37)H(38)O(6), the non-fused C atom belonging to the five-membered ring of the fluorene system is connected to two p-phenyl-ene rings, the rings opening up the C(ar-yl)-C-C(ar-yl) angle to 113.1?(1)°. The four-atom -O-CH(2)-C(=O)-O- chain between the p-phenyl-ene ring and the tert-butyl group assumes a more regular W-shaped conformation for one substituent [O-C-C-C torsion angle = 171.9?(2)°] but a less regular W-shaped conformation for the other [torsion angle = 147.4?(2)°].

Dimethyl 2,2'-({2,2'-methyl-enebis[6-(2H-benzotriazol-2-yl)-4-(2,4,4-trimethyl-pentan-2-yl)-2,1-phenyl-ene]}di-oxy)diacetate.

Project description:The asymmetric unit of the title compound, C(47)H(58)N(6)O(6), comprises three independent mol-ecules, in one of which one tert-butyl group is disordered in a 1:1 ratio. The mol-ecule is a di(ar-yl)methane having two aliphatic and one N-heterocyclic substituent in each aryl ring. For the mol-ecule having the disordered tert-butyl group, the aryl rings make an angle of 115.3 (2)° at the methyl-ene carbon; one aryl ring is aligned at 42.0 (1)° with respect to the N-heterocyclic substituent and the other at 48.7 (1)° with respect to its substituent. The two ordered mol-ecules are disposed about a pseudo center of inversion. The pairs of twist angles in these two mol-ecules differ [52.7 (1) and 61.7 (1)°, and 29.1 (1) and 58.5 (1)°].

Project description:The centrosymmetric title mol-ecule, C(28)H(32)N(2)O(2), has a central benzene ring subsituted in the 1- and 4-positions by (ethene-2,1-di-yl)pyridine groups, and in the 2- and 5-positions by but-oxy groups. The whole mol-ecule is X-shaped and relatively flat, the dihedral angle between the pyridine and the central benzene ring being 11.29?(10)°. In the crystal, neighboring mol-ecules are linked by weak C-H?N inter-actions, forming a two-dimensional undulating network.

2,2'-Dimethyl-2,2'-(m-phenyl-ene-dimethyl-ene)propane-dinitrile.

Project description:The title compound, C(16)H(14)N(4), features an aromatic ring with two 2,2'-dicyano-propyl residues in positions 1 and 3, which are located above and below the ring plane. The two residues differ in their conformation with respect to the aromatic ring: whereas one of the C(meth-yl)-C-C(methyl-ene)-C(aromatic) torsion angles is gauche [68.93?(12)°], the other one is fully staggered [177.63?(9)°]. The crystal structure is stabilized by C-H?N hydrogen-bonding inter-actions.
