Assembly of a phospho-molybdic Wells–Dawson-based silver coordination polymer derived from Keggin polyoxoanion cluster

Abstract

A 2D Wells–Dawson-based silver(I) coordination polymer was achieved based on silver-Schiff base building blocks and [P₂Mo₁₈O₆₂]⁶⁻ clusters using AgNO₃, N,N′-bis(furan-2-ylmethylene)hydrazine and Keggin [PMo₁₂O₄₀]³⁻ as original materials at room temperature. It is structurally characterized by IR spectroscopy, ³¹P NMR, XRPD, thermogravimetric (TG) analyses and X-ray crystallography. The structure of 1 exhibits a novel crystalline 2D coordination polymer constructed by the coordination interaction between the Wells–Dawson polyoxoanion [P₂Mo₁₈O₆₂]⁶⁻ and Ag–L species. The luminescent property of 1 in the solid state is investigated.
