An acentric luminescent cadmium dimethylsuccinate/bipyridine coordination polymer with an uncommon three-dimensional CdSO4 topology

The acentric coordination polymer {[Cd(dms)(4,4′-bpy)(H2O)2] · H2O}n (1, dms = 2,2-dimethylsuccinate, 4,4′-bpy = 4,4′-bipyridine) has been prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction, IR and thermogravimetric analysis. Fourfold one-dimensional (1-D) homochiral right-handed helical [Cd(dms)]n chain motifs are conjoined through tethering 4,4′-bpy ligands to construct a three-dimensional (3-D) network with uncommon CdSO4 (658) topology. Irradition of 1 with ultraviolet light results in blue–violet luminescence.
