Three new low-dimensional organic inorganic hybrid metal halides: Syntheses, structures and properties.

It is well known that organic inorganic hybrid metal halides have been excellent materials in the field of luminescence. So far, organic-inorganic Pb(Ⅱ) halide hybrids materials have been extensively studied for their excellent optical properties. However, the toxicity of lead may generate additional pollution. It is important to develop new lead-free halide hybrids. In this work, three new organic inorganic hybrid metal halides, namely [(C 4 H 10 NO)Ag 2 I 3 ] (1), [(C 4 H 10 NO) 2 CuI 2.5 ]·0.5I·0.5H 2 O (2) and [(C 4 H 9 NO) 2 CdI 2 ] (3) were synthesized under mild conditions. Compounds 1 and 2 display different one dimensional inorganic chains surrounded by organic amine cations, while compound 3 shows a zero dimensional structure. Their luminescent and optical properties were investigated in detail. The result suggests that these three compounds are potential optical materials. [Display omitted] • Three new organic inorganic hybrid metal halides were synthesized under mild conditions. • Three new compounds show various structures. • The results suggest that these three compounds are potential optical materials.
