Benzene-1,3,5-tricarboxylic acid–1,2-bis(1,2,4-triazol-4-yl)ethane–water (4/1/2)
The title compound, 4C(9)H(6)O(6)·C(6)H(8)N(6)·2H(2)O, crystallizes in a layer structure where each sheet is composed of anellated hydrogen-bonded rings of six distinct sizes: R(2) (2)(16), R(3) (3)(18), R(4) (4)(12), R(4) (4)(18), R(4) (4)(22) and R(4) (4)(25). The two largest rings, viz. R(4) (4)(22) and R(4) (4)(25), are associated with O-H⋯N bonds from the carboxyl groups to the triazole ri...

متن کامل4-Amino-3,5-bis(2-pyridyl)-4H-1,2,4-triazole–benzene-1,2,3-tricarboxylic acid–water (1/1/2)
Cocrystallization of 4-amino-3,5-bis-(2-pyrid-yl)-1,2,4-triazole (2-bpt) with hemimellitic acid (benzene-1,2,3-tricarboxylic acid) dihydrate (H(3)HMA·2H(2)O) produces the supra-molecular title compound, C(12)H(10)N(6)·C(9)H(6)O(6)·2H(2)O. Inter-molecular N-H⋯N hydrogen bonds are observed between the terminal pyridyl and amino groups of the 2-bpt molecule and the dihedral angles between the cent...
متن کامل1,4-Bis(4-pyridylmethoxy)benzene
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.
متن کامل1,4-Bis(4-aminophenoxy)benzene
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.
