Two-dimensional network acquired by Pb(II)–2-aminoethanethiolate

The combination of an equivalent amount of Pb(NO3)2 and 2-aminoethanethiol hydrochloride in the presence of a base yielded a two-dimensional network consisting of [PbCl(SCH2CH2NH3)](NO3) (1) units. The network is further extended to a three-dimensional framework with intermolecular hydrogen bonding involving NO3- and Cl−. The geometry around Pb in 1 can be best described as distorted pentagonal bipyrimidal with the axial positions occupied by Cl atoms. Due to the presence of a weak PbCl bond, the two-dimensional network can be considered to be formed of PbS2Cl units with an additional Cl acting as bridging atom.
