The synthesis and chiral crystal structures of two enantiomers of a Ag helical coordination polymer based on argentophilicity

Achiral ligand- and Ag( i )-driven spontaneous resolution occurred simultaneously in the formation of two enantiomers 1P and 1M of [Ag 2 (5-nip)(mpyz)] (5-nip = 5-nitroisophthalic, mpyz = 2,3,5,6-tetramethylpyrazine), whose absolute sense of a helix made of achiral components is induced by the metal Ag( i ) through argentophilic interactions.
