An unusual zig-zag 2D copper(I) coordination polymer as an outstanding catalyst for azide-alkyne "click" chemistry at room temperature.

A straightforward method for the synthesis of a two-dimensional (2D) new copper(I) coordination polymer, namely Cu(bzpdc), containing the ligand benzophenone 4,4'-dicarboxylate, and its effective use as catalyst for the azide-alkyne click chemistry at room temperature is reported. Zig-zag formation caused by cuprophilic interactions resulted in an unprecedented crystal structure with a very high copper content (45.5% by weight).
