A new heterometallic multiligand 3D coordination polymer: synthesis and structure of [Pb(OH)]n[Ag(SCN)(CN)]n.

The synthesis and structural characterization of a new coordination polymer [Pb(OH)]n[Ag(SCN)(CN)]n, formed by an anionic layer [Ag(CN)(µ3-SCN)]nn- linked to the 1D cationic fragment [Pb(OH)]n through a bridging cyanide is reported. We have obtained a rational combination of the pattern of laurionite-type structures ( Pb(OH)X, with X=halogen, SCN) with the 2D hexagonal pattern of the silver thiocyanate. The title compound shows luminescent behaviour, and the analysis of the computed band structure allow us to describe the electronic transitions.
