Structure and Photoluminescence of a New 3D Cu4I4 Hybrid Constructed by a Flexible Acyclic Aliphatic Diamine with Steric Effect
摘要:
A new 3D copper(I) iodide hybrid, [Cu4I4(TMEDA)2]n (1, TMEDA=N,N,N',N'-tetramethylethylenediamine), has been solvothermally synthesized and characterized by singlecrystal X-ray diffraction, IR spectroscopy, elemental analysis, powder X-ray diffractions and thermogravimetric analysis. Compound 1 crystallizes in tetragonal space group P42/n with a=b=11.5663(7) Å, c=9.2456(11) Å, V=1236.87(18) Å3, Z=8, C3H8CuIN, Mr=248.54, Dc=3.507 g/cm3, F(000)=920, μ(MoKα)=8.388 mm-1, the final R=0.0244 and wR=0.0573 for 1118 observed reflections (I>2σ(I)). The hybrid framework is built up from cubane-like Cu4I4 cluster and flexible acyclic aliphatic diamine TMEDA, which can be simplified into a twofold interpenetrating dia network. The solid state luminescence spectrum displays a strong yellow emission band at room temperature (λex=340 nm, λem=530 nm). Results reveal that steric effect of N-substituted methyl groups in TMEDA have obvious influence on the structure and photoluminescent property of compound 1.
