ABSTRACT=A chair 3D Co(II) phosphite frameworks have been prepared by ionothermal method.  It belongs to chiral space group P3221 and the whole framework can be topologically represented as a chiral 4-connected qtz net. It shows multi-step dielectric response arising from the reorientation of the Me2-DABCO in the chiral cavities. It also can be served as pron conductor with high conductivity, 1.71 × 10-3 S•cm-1, at room temperature, which is attributed to the formation of denser hydrogen-bonding networks providing efficient proton-transfer pathways.
