摘要
A new 3D copper（I） iodide hybrid, [Cu4I4（TMEDA）2]n （1, TMEDA = N,N,N＇,N＇- tetramethylethylenediarnine）, has been solvothermally synthesized and characterized by single- crystal 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） A, c = 9.2456（11） A, V= 1236.87（18） A3, Z = 8, C3H8CuIN, Mr = 248.54, Dc = 3.507 g/cm3, F（000） = 920, μ（MoKa） = 8.388 mm-1, the final R = 0.0244 and wR = 0.0573 for 1118 observed reflections （I 〉 20（/））. 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.
