A nano-scale triangular ring cluster of indium–selenide: the structure and templating effect

Abstract

Different from the dominating supertetrahedral structure of InSe clusters, co-assembled nano-scale In₃₃Se₆₀ triangular ring clusters and wheel-shaped In₁₈Se₃₀ clusters have been found. The unusual second-sphere coordination templating effect of the Mn(dach) complexes and the central Mn²⁺ ion is responsible for the formation of the triangular ring. The optical and electronic properties are discussed.
