4,4'-[(5-Carb-oxy-1,3-phenyl-ene)bis-(-oxy)]dibenzoic acid.

ABSTRACT: In the title compound, C(21)H(14)O(8), the central benzene ring makes dihedral angles of 77.8?(6) and 75.9?(5)° with the outer benzene rings. In the crystal, mol-ecules are linked by O-H?O hydrogen bonds involving carboxyl groups, forming one-dimensional ladders. Two-dimensional layers are formed by inter-penetration of these one-dimensional ladders.

4,4'-[4,4'-Sulfonyl-bis-(p-phenyl-ene-oxy)]dibutanoic acid.

Project description:In the title compound, C(20)H(22)O(8)S, the dihedral angle between the two benzene rings is 81.6?(3)°. The benzene-connected portions of the alk-oxy substituents are almost coplanar with their respective rings [C-C-O-C torsion angles of 174.77?(17) and -178.5?(4)°]. One of the butanoic acid groups is disordered over two conformations with a site-occupancy ratio 0.719?(6):0.281?(6). In the crystal, pairs of O-H?O hydrogen bonds link the mol-ecules into infinite zigzag chains along [130].

Crystal structures and Hirshfeld surface analyses of 4,4'-{[1,3-phenyl-enebis(methyl-ene)]bis-(-oxy)}bis-(3-meth-oxy-benzaldehyde) and 4,4'-{[(1,4-phenyl-ene-bis(methyl-ene)]bis-(-oxy)}bis-(3-meth-oxy-benzalde-hyde).

Project description:The title compounds, C24H22O6 (I) and C24H22O6 (II), each crystallize with half a mol-ecule in the asymmetric unit. The whole mol-ecule of compound (I) is generated by twofold rotation symmetry, the twofold axis bis-ecting the central benzene ring. The whole mol-ecule of compound (II) is generated by inversion symmetry, the central benzene ring being located on an inversion center. In (I), the outer benzene rings are inclined to each other by 59.96 (10)° and by 36.74 (9)° to the central benzene ring. The corresponding dihedral angles in (II) are 0.0 and 89.87 (12)°. In the crystal of (I), mol-ecules are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming ribbons propagating along the [10] direction. In the crystal of (II), mol-ecules are linked by C-H⋯O hydrogen bonds, forming a supra-molecular framework. The Hirshfeld surface analyses indicate that for both compounds the H⋯H contacts are the most significant, followed by O⋯H/H⋯O and C⋯H/H⋯C contacts.

1,3-Di-4-pyridylpropane-4,4'-oxy-dibenzoic acid (1/1).

Project description:The hydro-thermal reaction of Cd(NO(3))(2)·4H(2)O, 1,3-di-4-pyridylpropane (BPP) and 4,4'-oxydibenzoic acid (OBA) led to the formation of the title compound, C(13)H(14)N(2)·C(14)H(10)O(5). The asymmetric unit consists of one mol-ecule of OBA and one of BPP. In the OBA mol-ecule, one COOH group is nearly planar with its attached benzene ring [dihedral angle = 0.9 (1)°], while the other COOH group is slightly twisted with a dihedral angle of 10.8 (3)°. The carboxyl groups form strong inter-molecular O-H⋯N hydrogen bonds with N atoms of the pyridine rings in BPP, linking the mol-ecules into zigzag chains.

4,4'-(Propane-1,3-di-yl)dibenzoic acid.

Project description:The complete molecule of the title compound, C(17)H(16)O(4), is generated by crystallographic twofold symmetry, with the central C atom lying on the rotation axis and a dihedral angle between the benzene rings of 81.9 (2)°. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonding between carboxyl groups, forming one-dimensional supra-molecular chains.

(2-Meth-oxy-1,3-phenyl-ene)diboronic acid.

Project description:The mol-ecular structure of the title compound, 2-CH(3)O-C(6)H(3)-1,3-[B(OH)(2)](2) or C(7)H(10)B(2)O(5), features two intra-molecular O-H⋯O hydrogen bonds of different strengths. One of the boronic acid groups is almost coplanar with the aromatic ring, whereas the second is significantly twisted. Mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds, generating infinite chains cross-linked to form a two-dimensional sheet structure aligned parallel to the (01) plane.

4,4'-{[1,2-Phenyl-enebis(methyl-ene)]bis-(-oxy)}di-benzoic acid di-methyl-formamide disolvate.

Project description:In the title solvate, C22H18O6·2C3H7NO, the complete dicarboxylic acid molecule is generated by a crystallographic twofold axis, which bisects the central benzene ring and one N,N-di-methyl-formamide solvent mol-ecule. The dihedral angle between the central and pendant benzene rings is 54.53?(5)° while that between the pendant rings is 45.44?(5)°. In the crystal, the acid molecules are linked to the solvent molecules via O-H?O and weak C-H?O hydrogen bonds. Further weak C-H?O inter-actions link adjacent acid mol-ecules into a three-dimensional network.
