N,N′-Bis(3-phenylprop-2-en-1-ylidene)-2,2′-disulfanediyldianiline

Abstract

In the title compound, C30H24N2S2, the two phenyl rings attached to the S atoms are oriented nearly perpendicularly, making a dihedral angle of 86.14 (8)°. Each of the two ArCH=CHCH=N units is almost planar, having maximum deviations from the least-squares planes of 0.125 and 0.149 Å, and rotated around the C—N bonds relative to the adjacent phenyl ring by 110.26 and 30.30°.

New Zn(II) complexes with N2S2 Schiff base ligands. Experimental and theoretical studies of the role of Zn(II) in disulfide thiolate-exchange

“…The crystal structure of the ligand L 1 has been reported previously [27]. By means of an independent X-ray structure determination (results available upon request) we were able to confirm this result and proved that our L 1 material is the disulfide Schiff base ligand shown in Scheme 2.…”

“…By means of an independent X-ray structure determination (results available upon request) we were able to confirm this result and proved that our L 1 material is the disulfide Schiff base ligand shown in Scheme 2. According to [27], bond lengths and angles in the central CÀSÀSÀC group of L 1 are SÀS = 2.0302(6) Å, CÀS = 1.782(2) and 1.779(2) Å, and CÀSÀSÀC = À86.14(8)°at 100 K, while our own values were similar but obtained at room temperature.…”

“…The Schiff base ligand L 1 was prepared as reported elsewhere [27]. Infrared spectra from KBr pellets were collected on a FT-IR JASCO 680 plus spectrophotometer in the range 4000-400 cm…”
