Query: Honeycomb-structure RuI3, a new quantum material related to
  {\alpha}-RuCl3   The Kitaev model predicts that quantum spin liquids (QSLs) will form at low
temperatures under certain special conditions, and materials hosting the QSL
state are frequently sought. The layered honeycomb lattice material
{\alpha}-RuCl3 has emerged as a prime candidate for displaying the Kitaev QSL
state. Here we describe a new polymorph of RuI3 with a layered honeycomb
lattice structure, synthesized at moderately high pressures and stable under
ambient conditions. Preliminary characterization reveals metallic, paramagnetic
behavior, the absence of long-range magnetic order down to 0.35 K and an
unusually large T-linear contribution to the heat capacity at low temperatures.
We propose that this RuI3 phase, with a layered honeycomb lattice and strong
spin-orbit coupling, provides a new route for the characterization of quantum
materials.
