A new polar perovskite coordination network with azaspiroundecane as A-site cation

Abstract

ABX₃ perovskite coordination networks are a rapidly growing sub-class of crystalline coordination networks. At present, synthetic efforts in the field are dominated by the use of commercially available building blocks, leaving the potential for tuning properties via targeted compositional changes largely untouched. Here we apply a rational crystal engineering approach, using 6-azaspiro[5.5]undecane ([ASU]⁺) as A-site cation for the synthesis of the polar perovskite [ASU][Cd(C₂N₃)₃]_.
