- Аннотация: A complete screening of compositions of crystallizing products of hybrid perovskites in the most popular DMF/DMSO solvents is performed for various cations (FA+/MA+) and anions (I–/Br–). We found 4 new solvate phases of formamidinium hybrid perovskites, (FA)2Pb3I8*4DMF, FAPbI3*2DMF, (FA)5Pb2I9*0.5DMSO, and even the bromide solvate (FA)2PbBr4*DMSO. These compounds are observed for the first time and their refined crys-tal structures showed large cells of unique types dependent of solvent and perovskite compositions. We also monitored crystallization pathways of multi-compositional thin films and identified phases that are able to crystallize from mixed cation and anion solutions. Based on the obtained data, we performed a deep analysis of the structural peculiarities of all the solvate phases observed in the screened compositional space and dis-cussed how the solution composition would predetermine the early stages of crystallization of target perovskite films.
