Hydrothermal treatment of a mixture of [Zn(MeCO 2 ) 2 ]·H 2 O, terephthalic acid, and 2,2′‐bipyridine resulted in a coordination polymer [Zn(bpy)(tp)](bpy) ( 1 ; bpy = 2,2′‐bipyridine, H 2 tp = terephthalic acid) which crystallizes in the monoclinic space group C 2/ c , M r = 541.85, a = 15.388(11), b = 21.963(11), c = 7.670(8) Å, β = 112.82(2)°, V = 2387(3) Å 3 , Z = 4, D c = 1.506 g·cm −3 . An X‐ray single‐crystal structural analysis reveals that 1 is a three‐dimensional network with nanosized channels constructed from one‐dimensional coordination chains via C−H ··· O hydrogen bonds and aromatic intercalations. TGA and XRPD showed that the porous network of 1 is very stable while the guest 2,2′‐bipyridine molecules in the channels are removable. Compound 1 shows a strong ligand‐centred emission at room temperature in the solid state. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
