1,4-Bis(4-pyridylmeth-oxy)benzene.

ABSTRACT: The mol-ecule of the title compound, C(18)H(16)N(2)O(2), lies about a center of inversion. The central phenyl-ene ring is aligned at 62.7?(1)° with respect to the pyridyl ring. In the crystal, weak inter-molecular C-H?N hydrogen bonds link mol-ecules into sheets parallel to (104). C-H?O inter-actions are also present.

1,4-Bis(4-amino-phen-oxy)benzene.

Project description:The title compound, C(18)H(16)N(2)O(2), is a precusor for the synthesis of polyimides. The mol-ecule is located on a crystallographic inversion center and the terminal amino-phen-oxy rings are almost perpendicular to the central benzene ring with a dihedral angle of 85.40?(4)°. The mol-ecular conformation is stabilized by N-H?O and N-H?N inter-molecular hydrogen-bonding inter-actions.

1,4-Bis(6-chloro-pyrimidin-4-yl-oxy)benzene.

Project description:In the title compound, C(14)H(8)Cl(2)N(4)O(2), all atoms of the 6-chloro-pyrimidin-4-yl-oxy group and the C atoms at the para positions of the central benzene ring lie on a crystallographic mirror plane. The complete benzene ring is generated by the mirror plane and hence the dihedral angles between the pyrimidine rings and the benzene ring are exactly 90°. The crystal structure is stabilized by weak C-H?O and C-H?N hydrogen bonds.

Bis(acetato-?O)[1,2-bis-(2-pyridylmeth-oxy)benzene-?N,O,O',N']copper(II) monohydrate.

Project description:In the title compound, [Cu(CH(3)COO)(2)(C(18)H(16)N(2)O(2))]·H(2)O, the Cu(II) ion is six-coordinated in a typically Jahn-Teller distorted octa-hedral environment defined by two O and two N atoms from the ligand and two O atoms from acetate anions. A linear chain structure propagating in [010] is built up by inter-molecular O-H?O hydrogen bonds involving the uncoordinated water mol-ecules.

1,4-Bis(1,1-dimethyl-prop-yl)-2,5-dimeth-oxy-benzene.

Project description:The title compound, C(18)H(30)O(2), was prepared by Friedel-Crafts alkyl-ation of 1,4-dimeth-oxy-benzene with 2-methyl-2-butanol. The complete mol-ecule is generated by the application of a crystallographic centre of inversion. The two meth-oxy groups are oriented in the same plane of the aromatic ring [C-C-O-C torsion angle = 9.14?(16)°]. While one methyl group of the tert-pentyl substituent is coplanar with the benzene ring [C-C-C-C = 0.45?(15)°] and lies towards the less-hindered H atom, the other methyl and ethyl groups are directed to either side of the benzene ring [C-C-C-C torsion angles = 118.78?(12) and 59.11?(14)°, respectively]. In the crystal, the hydro-phobic mol-ecules pack to form a brick-wall-like architecture.

Bis(2-amino-pyridinium) 2,5-dicarb-oxy-benzene-1,4-dicarboxyl-ate.

Project description:In the title compound, 2C(5)H(7)N(2) (+)·C(10)H(4)O(8) (2-), the 2-amino-pyridinium (2-apyH) cation and 2,5-dicarb-oxy-benzene-1,4-dicarboxyl-ate (btcH2) anion are both nearly planar, with r.m.s. deviations of 0.015 and 0.050?Å, respectively. The angle between the latter least-squares planes is 17.68?(9)°. The overall crystal structure results from the packing of two-dimensional networks, formed by alternating 2-apyH and btcH2 linked by hydrogen bonds, parallel to (100).
