Abstract:

The polymeric compounds {Cd(bix)[(CH 3 O) 2 PS 2 ] 2 } n (1) and {Cd(bix)[(C 2 H 5 O) 2 PS 2 ] 2 } n (2) [bix=1,4-bis(imidazole-l-ylmethyl)benzene; (CH 3 O) 2 PS 2 = O , O ′-dimethyldithiophosphate; (C 2 H 5 O) 2 PS 2 = O , O ′-diethyldithiophosphate] have been synthesized and characterized by single-crystal structure determinations, elemental analyses, and IR spectra. X-ray diffraction studies revealed that they exhibit one-dimensional polymeric structures with a zigzag chain for 1 and a linear chain for 2, connected by π – π stacking interactions to form 2D networks. Their solid-state luminescent properties were also studied. Crystal data for 1 at−100°C: monoclinic, space group C 2/ c , a =18.5196(7), b =10.2337(3), c =14.0241(11)Å, β =90.190(2)°, Z =4, R 1 =0.0362; for 2 at−100°C: triclinic, space group , a =8.9837(10), b =9.5038(0), c =10.4893(0)Å, α =65.706(9), β =77.856(10), γ =73.184(10)°, Z =1, R 1 =0.0316.
