Abstract

We report the successful crystal growth of a previously unknown mixed-metal organic compound (CH₃NH₃)₂AgInBr₆. This phase, which is not obtained by direct combination of reactants, is crystallized through the use of Pb²⁺ (from CH₃NH₃PbBr₃) to modulate the soluble intermediates and force formation of (CH₃NH₃)₂AgInBr₆. Our results provide insights into mechanism and design-driven crystal growth and discovery of new halide materials that are chemically related to perovskites with photovoltaic and related applications.
