A trimetallic macrocycle : Starting from nonlinear N‐deprotonated benzimidazole and square‐planar cyclometalated platinum( II ) precursors, cyclic trimers with three metal vertices can be obtained by a general and rational strategy (shown schematically, M=Pt). A complex is formed with 2‐(2‐thienyl)pyridine as chelating ligand which photoluminesces in solution at room temperature.
