A quasiracemate is the cocrystallization of two similarly shaped but chemically distinct molecules of opposite handedness. There has been limited to no work regarding quasiracemates in the field of inorganic chemistry. The goal of this study was to prepare various metal based enantiomers, racemates, and quasiracemates using N-benzoylalanines with imidazole or N-methylimidazole as ligands bound to copper to form a metal complex. In this study, we developed a method to prepare substituted N-benzoylalanines and its copper complexes. We also prepared one co-crystal between two differently substituted N-benzoylalanines.
This work reports the successful synthesis and crystal structure analysis of an organic quasiracemate, (D-4-nitro-N-benzoylalanine)(L-4-methyl-N-benzoylalanine), an inorganic quasiracemate, bis(N-methylimidazole)(D-4-nitro-N-benzoylalanine)(L-4- methyl-N-benzoylalanine)copper(TT), and a racemate bis(N-methylimidazole)bis(D,L-4-nitro-N-benzoylalanine)copper(TT).
