Three novel homochiral helical metal-organic frameworks (MOFs), namely [Zn(LTP) 2 ] n (1), [Cd(LTP) 2 ] n (2), and [Ni(LTP) 2 ] n (3) (LTP = L-thioproline), have been synthesized and characterized. X-ray crystallographic analysis shows that all the three complexes consist of homochiral left-handed or right-handed helical chains. Complex 1 exhibits 1-D Zn-carboxyl right-handed helical chains constructed by pentacoordinated Zn 2þ ions. Complex 2 shows a 2-D homochiral coordination framework with (4, 4) topology based on Cd-carboxyl right-handed helical chains in which Cd 2þ ions are 6-fold coordinated. There are various hydrogen bonds between the adjacent helical chains in 1 and 2 which connect them into 3-D supramolecular networks. Complex 3 also exhibits a 2-D homochiral layer structure with (4, 4) topology containing Ni-carboxyl left-handed helical chains. The luminescence properties of 1 and 2 have been investigated briefly.
