چکیده
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.

In the hydro-thermally prepared title coordination polymer, [Ni(C(2)H(6)NO(3)S)(2)(C(12)H(10)N(4))](n), the Ni(II) ion and the 1,4-bis-(1H-imidazol-1-yl)benzene ligand occupy special positions on inversion centers. The metal ion shows a slightly distorted octa-hedral coordination geometry, being linked to two N atoms of two 1,4-bis-(imidazol-1-yl)benzene ligands and to two O and two N atoms of ...

In order to gain more molecular electronic data, HOMO and LUMO of compound 6 have been calculated by Gaussian 03 W.
متن کاملFour tetrairidium carbonyl clusters linked by six diphosphino ligands: synthesis and X-ray structure of [{Ir(4)(CO)(9)}(4)(dppmb)(6)] (dppmb = 1,4-bis(diphenylphosphinomethyl)benzene.
Tetrairidium carbonyl clusters are potentially useful connectors for multidimensional functionalized frameworks with organic bis-phosphines as linkers. The reaction of Ir(4)(CO)(12) and 1,4-bis(diphenylphosphinomethyl)benzene produces an oligomeric cyclic structure, made of 4 connectors and 6 linkers, a possible intermediate in the formation of three dimensional networks.
متن کاملPreparation of 1,4-bis(4-methylstyryl)benzene nanocrystals by a wet process and evaluation of their optical properties
Single-crystal 1,4-bis(4-methylstyryl)benzene is a promising material for optoelectronic device applications. We demonstrate the preparation of 1,4-bis(4-methylstyryl)benzene nanocrystals by a wet process using a bottom-up reprecipitation technique. Scanning electron microscopy revealed the morphology of the nanocrystals to be sphere-like with an average particle size of about 60 nm. An aqueous...
