Аннотация

A 1D cadmium (II) coordination polymer {[Cd 2(L) 3Cl 3]×Cl} n (1) (L = 1,3-bis(benzimidazol-l-yl)-2-propanol) is synthesized by the hydrothermal reaction and characterized by elemental analysis, IR, TG, and X-ray single crystal diffraction. Compound 1 crystallizes in the hexagonal system, space group P 63/ m with a = 15.4857(11) Å, b = 15.4857(11) Å, c = 14.478(2) Å, γ = 120°, V = 3006.8(5) Å 3, Z = 2. In the structure of complex 1, each cadmium center is hexahedrally coordinated by three chlorine atoms and three nitrogen atoms of three distinct L ligands. A detailed analysis reveals that compound 1 exhibits a 1D chain of beads and the adjacent chains are further linked by C-H⋯Cl hydrogen bonding to form a 2D supramolecular framework. Furthermore, the solid-state fluorescent property of 1 is investigated at room temperature.
