Synthesis and Characterization of Two New Chiral Copper(II) Compounds Constructed from (+)‐ N ‐Tosyl‐ L ‐glutamic Acid

Chiral coordination polymers have attracted intense interest mainly due to their potential applications. Hence, two new chiral copper(II) coordination polymers {[Cu(tsgluO)(H 2 O)] 2 ·3H 2 O} n ( 1 ) and [Cu(tsgluO)(2,2′‐bipy)] n ( 2 ) (H 2 tsglu(+)‐ N ‐tosyl‐l‐glutamic acid; 2,2′‐bipy2,2′‐bipyridine) were synthesized in the absence or presence of 2,2′‐bipy ligand and structurally characterized. A single crystal X‐ray diffraction study revealed that compound 1 consists of a paddle‐wheel dicopper(II) core, which links other equivalents via four tsgluO 2− ligands to form a 1D double chain. Such a chain is further interconnected through weak π‐π stacking and hydrogen bonding interactions to form a 3D H‐bonded supramolecular structure with 1D channels hosting lattice water molecules. Whereas, compound 2 , containing the coordinating 2,2′‐bipy, gives rise to a ladder‐like 1D double chain. Antiferromagnetic interactions were observed in 1 and 2 .
