A two-dimensional Cd^II coordination polymer with 2,2′-(disulfane­diyl)dibenzoate and 1,10-phen­anthroline ligands

A new two-dimensional cadmium(II) coordination polymer containing 44-membered metallamacrocycles and helical chains has been prepared under solvo­thermal conditions using flexible 2,2′-(disulfane­diyl)di­benzoate and 1,10-phenanthroline ligands.

Poly[([mu]₅-3-carb­oxy­benzene-1,2-di­carboxyl­ato)lead(II)]: a helical lead(II) coordination polymer

A chiral two-dimensional lead(II) coordination polymer containing right-handed helical chains has been prepared under hydro­thermal conditions using an achiral organic 3-carb­oxy­benzene-1,2-di­carboxyl­ate linker ligand. The thermogravimetric and optical properties are also reported.
