The quantum kagome antiferromagnets YCu3(OH)6OxCl3-x (x=0,1/3) are producedusing a unified solid state synthesis route for polycrystalline samples. Fromstructural refinements based on neutron diffraction data, we clarify thestructure of the Y3Cu9(OH)18OCl8 (x=1/3) compound and provide a revisedchemical formula. We use muon spin relaxation, as a local probe of magnetism,to investigate the exotic low temperature properties in the two compounds. Inagreement with the low temperature neutron diffraction data, we find noevidence for long range ordering in both materials but they exhibit distinctground states: while disordered static magnetism develops in the x=0 compound,we conclude on the stabilization of a quantum spin liquid in the x=1/3 one,since the local fields remain fully dynamical. Our findings are in contrast toprevious reports based on thermodynamical measurements only. We then discusstheir origin on the basis of structural details and specific heat measurements.In particular, the x=1/3 compound appears to realize an original spatiallyanisotropic kagome model.
