Synthesis, Crystal Structure and Luminescent Property of Cadmium Complex Based on 2-(2-(1Hbenzo[d]imidazol-2-yl)benzyl)-1H-benzo[d]-imidazole
摘要:
The complex [Cd(bbb)Cl2]·DMF·H2O, where bbb is 2-(2-(1H-benzo[d]imidazol-2-yl)benzyl)-1H-benzo[d]imidazole, was synthesized and characterized by X-ray single-crystal structure analyses. For the complex: C24H25Cl2CdN5O2, Mr=598.77, crystal system, triclinic, space group P1, a=9.9878(12), b=10.0008(12), c=13.2217(15)Å, α=80.674(2), β=72.158(2), γ=86.776(2)°, V=1240.5(3)Å3, Z=2, Dc=1.598 g/cm3, λ=0.71073Å, μ(MoKα)=1.127 mm-1, F(000)=600, S=1.04, R=0.0905 and wR=0.3088 for 4805 observed reflections with I>2σ(I). It is a neutral complex. The distorted tetrahedral geometry of cadmium ion is coordinated by two nitrogen atoms of ligand and two chloride ions. The complex emits blue green luminescence with emission peaks at 480 nm in DMF solution.
