The hydrothermal reactions of Zn(ClO 4 ) 2 ·6H 2 O and Cd(ClO 4 ) 2 ·6H 2 O with 1,3‐bis(2 H ‐tetrazol‐5‐yl)benzene in an aqueous ethanol and an aqueous methanol/pyridine medium, respectively, yielded a 3D and a 2D metal‐organic coordination framework [Zn(1,3‐BTB)] ( 1 ) and [Cd(1,3‐BTB) 2 (Py) 2 (H 2 O) 2 ] [Cd[Cd(Py)(H 2 O)] 2 (1,3‐BTB) 2 ] ( 2 ) (1,3‐BTB = 1,3‐ditetrazolylbenzene, Py = pyridine), respectively. Species 1 possesses an open network structure with no guest molecules residing in its small cavities. The structural characterisation of 2 shows a 2D layered framework consisting of nano‐sized polytube structures which are stacked one on top of another in the (110) plane giving small channels along the b and c axes. Additionally, compounds 1 and 2 exhibit strong fluorescence at room temperature in the solid state. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
