Self-assembly, crystal structure and photoluminescent properties of a novel organic–inorganic hybrid coordination polymer: [CdCl3(CH3)3NH]

A novel organic–inorganic coordination polymer [CdCl3(CH3)3NH] 1 was synthesized by the reaction of CdCl2 with trimethylamine (TMA) at 170 °C for 5 days in ethanol and structurally characterized by means of X-ray single diffraction. The title compound affords a one-dimensional chain structure. It crystallizes in hexagonal system space group P6(3)/mP6(3)/m with a=9.1401(13)Å, b=9.1401(13)Å, c=6.7313(13)Å, γ=120.00°γ=120.00°, V=487.00(14)Å3, Z=2Z=2, DC=1.895Mg/m3, F(000)=266F(000)=266, Mr=277.86Mr=277.86, μ(MoKα)=2.99mm−1, the final R=0.0420R=0.0420 and ωR=0.1020ωR=0.1020 for 355 observed reflections with I>2σ(I)I>2σ(I). The title compound consists of cation [(CH3)3NH]+ and anion chain [(CdCl3)]n−, and they are combined by static attracting forces in the crystal. TG–DTA, XRD and IR data for the title compound are reported and discussed. The photoluminescent properties of the compound 1 were also investigated.
