The single crystal X-ray data of six crystals show that the stellate crystals are chiral metalorganic frameworks formed by a single continuous network (Figures and). The chirality is expressed in the molecular arrangements at different levels: At the molecular level, the metal-pyridine coordination chemistry resulted in two types of helicoidal channels and homochiral metal nodes. Four pyridine units belonging to different ligands are arranged in a propeller-like fashion around the Cu 2+ centers. The axial positions are occupied by co-ligands (water molecules, Cl and/or SO4 2-). The two sets of channels are parallel to the c-axis. Hexagonal channels centered around the 6-fold axis are surrounded by six identical trigonal channels. The shapes of the channels follow the six-fold and threefold symmetry elements of the space group.
