Non-centrosymmetric packing of 1-D coordination networks based on chirality

Using CoCl2 and a chiral tecton possessing C2 chirality and based on two coordination poles composed of a pyridine unit connected at the 4-position to a pyridine bearing at the 2 and 6 positions two optically active oxazoline moieties, a polar solid is obtained. The latter results from the acentric packing of directional 1-D coordination networks.
