Abstract

Two enantiomorphic MgII/carboxylate coordination polymers [Mg(bpda)(H2O)4]n (1M and 1P) have been obtained by spontaneous resolution from achiral precursors, 2,2′-bipyridyl-3,3′-dicarboxylic acid (H2bpda) and Mg(NO3)2·6H2O, upon crystallization without any chiral auxiliary. X-ray structural analysis shows that chiral transmission from molecular axially chiral conformations to crystal chirality is established through concerted coordination and H-bonding interactions. In addition, the CD data, and the thermal and photoluminescence properties in the solid state have also been discussed.
