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

Abstract

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 allows us to describe the electronic transitions.
