Four two-dimensional highly undulating silver(I)-hexamethylenetetramine co-ordination networks containing micropores

Four interesting polymers, namely [Ag-2(mu (3)-hmt)(2)(MeCN)](ClO4)(2) 1, [Ag(mu (3)-hmt)(ma)] 2, [Ag(mu (3)-hmt)(ba)] . H2O 3 and [Ag(mu (3)-hmt)(sal)].H2O 4 (hmt=hexamethylenetetramine, ma=malonate, ba=benzoate and sal=salicylate) have been synthesised and structurally characterised by X-ray diffraction. In these complexes, the two-dimensional [Ag(mu (3)-hmt)] layers of hexagonal units are highly undulating and each pair of adjacent lateral ligands, MeCN or carboxylates, at the same side of the layers are slanted towards each other, resulting in intralayer micropores.
