Abstract An undecanuclear copper(I)‐based coordination polymer with formula [Cu 11 Br 5 (amtd) 6 (MeCN) 3 ] ( 1 ) is accessible by mixed‐solvothermal reaction of copper(I) bromide with 2‐amino‐5‐mercapto‐1,3,4‐thiadiazole (Hamtd) in acetonitrile and water. X‐ray structural analysis reveals that 1 has an acs topological network based on six‐connected {Cu 11 Br 2 S 6 } building blocks, interconnected by amtd – linkers. The undecanuclear copper cluster adopts the geometry of a bicapped trigonal prism, in which each triangular face of the {Cu 5 S 6 } trigonal prism is capped by an additional {Cu 3 Br} trigonal pyramid. The undecanuclear copper cluster is not common, and the discussion of the crystal structure is provided. IR spectroscopy, elemental analysis, and powder XRD analysis confirmed the phase‐purity of the as‐synthesized compound. The photoluminescence properties of 1 in the solid state at ambient temperature are also investigated.
