  We report superconductivity in the honeycomb-lattice pnictide SrPtAs with Tc
= 2.4 K. To our knowledge, SrPtAs is the first superconducting pnictide with a
honeycomb lattice structure. Our finding opens up new playground to develop
pnictide superconductors with honeycomb lattices, in addition to square
lattices known in iron-based superconductors.
