Abstract

We report a novel multilayered organic-inorganic hybrid material, β”-(BEDT-TTF)2[(H2O)(NH4)2Rh(C2O4)3].18-crown-6. This is the first molecular superconductor to have a superlattice with layers of both BEDT-TTF and 18-crown-6, and also the first with the anion tris(oxalato)rhodate. This is the 2D superconductor with the widest gap between conducting layers where only a single donor packing motif is observed (β”). The strong 2D nature of this system strong-ly suggests that the superconducting transition is a KT transition. A superconducting Tc of 2.7 K at ambient pressure was found by transport and 2.5 K by magnetic susceptibility measurements.
