On February 24, 2018, Shi, Ya-Jing; Song, Hui-Hua published an article.Safety of H-Phg(4-OH)-OH The title of the article was Three enantiomeric pairs of zinc(II) homochiral coordination compounds based on D-(-)- and L-(+)-4-Hydroxyphenylglycine: Synthesis, structures and luminescent properties. And the article contained the following:
Three enantiomeric pairs of novel homochiral coordination compounds (HCCs) with the formula {[Zn(D-hpg)(4,4′-bipy)(H2O)]·(NO3)}n 1-D, {[Zn(L-hpg)(4,4′-bipy)(H2O)]·(NO3)}n 1-L, {[Zn(D-hpg)(4,4′-bipy)(H2O)]·(ClO4)}n 2-D, {[Zn(L-hpg)(4,4′-bipy)(H2O)]·(ClO4)}n 2-L, [Zn(D-hpg)2(4,4′-bipy)]·(4,4′-bipy)·2H2O 3-D, [Zn(L-hpg)2(4,4′-bipy)]·(4,4′-bipy)·2H2O 3-L (D-Hhpg = D-(-)-4-Hydroxyphenylglycine, L-Hhpg = L-(+)-4-Hydroxyphenylglycine, 4,4′-bipy = 4,4′-bipyridine) have been synthesized and characterized by single-crystal X-ray diffraction, elemental anal., IR spectroscopy, thermal anal. and powder X-ray diffraction. Compounds 1 and 2 are isostructural 2D layer structures with NO-3 or ClO-4 anions between the layers. While compound 3 features a 0D structure without counter anions. Compounds 1-D and 2-D both contain 1D right-hand helical chains via D-Hhpg ligand, while 1-L and 2-L both contain 1D left-hand helical chains via L-Hhpg ligand. It’s worth noting that 3-D forms left-hand supramol. double helical chains, while 3-L forms right-hand supramol. double helical chains. Compounds 1-3 are further extended into 3D supramol. architectures through hydrogen-bonding interactions. CD and luminescent properties of compounds 1-3 were investigated at room temperature Our results highlight that chiral ligands have an important effect on regulating the chirality/helicity of complexes and the frameworks can be controlled via applying different zinc salts and adjusting the pH values. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).Safety of H-Phg(4-OH)-OH
