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=sali cylate) have been synthesised and structurally characterised by X-ray diffr action. In these complexes, the two-dimensional [Ag(mu (3)-hmt)] layers of hexagonal units are highly undulating and each pair of adjacent lateral lig ands, MeCN or carboxylates, at the same side of the layers are slanted towa rds each other, resulting in intralayer micropores.
