Two Photoluminescent Metal–Organic Frameworks Constructed from Cd3(μ3‐OH) Cluster or 1D Zn5(μ3‐OH)2(μ‐OH)2 Chain Units and In Situ Formed Bis(tetrazole)amine Ligands

Hydrothermal reactions of CdCl2·2.5H2O or ZnCl2, sodium dicyanamide, and sodium azide yield two interesting photoluminescent coordination polymers, namely, [Cd{Cd3(μ3‐OH)(dcadtzH)3(H2O)6}2] (1) and [Zn5(μ3‐OH)2(μ‐OH)2(dcadtz)2]·2H2O (2) [dcadtzH3 = bis(5‐tetrazolyl)amine], in which triangular [Cd3(μ3‐OH)]5+ cluster subunits in 1 and 1D [Zn5(μ3‐OH)2(μ‐OH)2]n6n+ chain subunits in 2 are linked by in situ generated bis(tetrazole)amine ligands to generate an interesting 2D coordination net and a 3D microporous metal–organic framework, respectively.
