Zn₂[(<i>S</i>)‐O₃PCH₂NHC₄H₇CO₂]₂: A Homochiral 3D Zinc Phosphonate with Helical Channels

Abstract

Three types of channel—right- (R) and left-handed (L) helical, and achiral (A)—alternate along the c axis in the structure of the title compound (see picture). The catalytically active groups of the 1-phosphonomethylproline ligands are directed into the channels, thus suggesting applications of this material in asymmetric catalysis.
