Entering a new phase: Tin sulfide (SnS) nano‐ and microcrystals were synthesized by a seedless, solution procedure. Three‐dimensional tetrahedral particles crystallized in the zinc blende (ZB) structure (see SEM image) while two‐dimensional platelike particles crystallized in the orthorhombic phase. The optical properties of the orthorhombic plates were similar to bulk SnS, but the absorption edge of the ZB tetrahedra was blue‐shifted by around 300 nm compared to that of bulk SnS.
