One-dimensional
(1D) chiral chain complexes [CuLSCu(Pydc)] (2S) and [CuLRCu(Pydc)] (2R)
(LS = (E)-3-(((1S,2S)-2-(((E)-3-oxo-3-(4-pyridin-4-yl)phenyl)propylidene)amono)-1,2-diphenyl)imino)-1-(4-(py-
ridi-4-yl)phenyl)butan-1-one) and LR = (E)-3-(((1R,2R)-2-(((E)-3-oxo-3-(4-pyridin-4-yl)phenyl)propyli-
dene)amono)-1,2-diphenyl)imino)-1-(4-(pyridi-4-yl)phenyl)butan-1-one and Pydc =
2,6-pyridinedicarboxylic acid) have been synthesized vis mononuclear chiral
enantiomer precursors CuLS (1S) and
CuLR (1R). Their different chiral
configurations of 1S, 1R, 2S and 2R were determined by
single-crystal X-ray diffraction analyses and further characterized by
elemental analyses, infrared spectra (IR), powder X-ray diffraction (PXRD), thermal
gravimetric analyses (TGA) and circular dichroism spectra (CD).
