Synthesis, Single‐Crystal Structure and Characterization of (CH3NH3)2Pb(SCN)2I2

Abstract
The perovskite phase (CH3NH3)2Pb(SCN)2I2 with a structure closely related to the K2NiF4-type was identified as the product of the reaction of CH3NH3I and Pb(SCN)2 by single-crystal X-ray analysis. This extends the range of suitable dyes for solar cell applications to a class of perovskite-related structures of the general composition (AMX3)n(AX)m.
