Two homochiral coordination polymers based on a chiral reduced Schiff base ligand, namely poly[(μ 5 ‐4‐{[(N R ,1 S )‐(1‐carboxylato‐2‐phenylethyl)amino]methyl}benzoato)zinc(II)], [Zn(C 17 H 15 NO 4 )] n , (1), and poly[(μ 5 ‐4‐{[(N R ,1 S )‐(1‐carboxylato‐2‐phenylethyl)amino]methyl}benzoato)cobalt(II)], [Co(C 17 H 15 NO 4 )] n , (2), have been obtained by hydrothermal methods and studied by single‐crystal X‐ray diffraction, elemental analyses, powder X‐ray diffraction, thermogravimetric analysis, IR spectroscopy and fluorescence spectroscopy. Compounds (1) and (2) are isostructural and crystallize in the P 2 1 2 1 2 1 space group. Both display a three‐dimensional network structure with a one‐dimensional channel, with the benzyl group of the ligand directed towards the channel. An investigation of photoluminescence properties shows that compound (1) displays a strong emission in the purple region.
