Abstract
- Abstract: One homochiral 1D coordination polymer [Cu(ATIBDC)(2,2′-bipy)]·3H2O·CH3OH (1) and three achiral 1D coordination polymers: [Cd(ATIBDC)(2,2′-bipy)(H2O)]·3H2O (2), [Cd(ATIBDC)(phen)(H2O)]·4H2O (3), and [Mn(ATIBDC)(phen)2]·5H2O (4) have been synthesized and characterized (H2ATIBDC=5-amino-2,4,6-triiodoisophthalic acid, 2,2′-bipy=2,2′-bipyridine, and phen=1,10-phenanthroline). Extended high dimensional network architectures are further constructed with the help of weak secondary interactions, such as hydrogen bonding, aromatic stacking, and halogen bonding (C–I…π and C–I…N/O). Complex 1 crystallizes in the monoclinic system with chiral space group P2(1) and exhibits a right-handed 21 helical chain structure. The homochirality of 1 was confirmed by CD spectrum. Interestingly, two new configurations of decameric water cluster are found in 3 and 4. The acyclic tetrameric cluster (H2O)3(CH3OH) in 1 and (H2O)4 in 2 array into highly ordered helical infinite chains. Thermal stabilities of all the complexes have been studied. Solid state fluorescent properties of the Cd(II) complexes have been explored. [Copyright &y& Elsevier]
