Synthesis and structure of 2D‐ and 3D‐ inorganic‐organic coordination polymers: based on Ag‐hmt subunit

Two new inorganic‐organic complexes, namely, [Ag2(hmt)2]Cr2O7·H2O (1) and [Ag(hmt)(tar)0.5]·H2O (2), (hmt = hexamethylenetetramine, Tar = tartarate,), have been synthesized in H2O/CH3CN solvent at room temperature. Both molecules have the common [Ag3hmt3]3+ layers. Compound 1 is a two‐dimensional structure, and Complex 2 shows three‐dimensional topology. In complex 2, the tartarate molecules are connected with adjacent layers to form parallelogram pores of 18.55×7.44 Å, which are occupied by two water molecules. (© 2004 WILEY‐VCH Verlag GmbH & Co.
