We report magnetization, electron-spin resonance (ESR), and muon-spin relaxation (μSR) measurements on single crystals of the S=1/2 (Cu+2) kagome compound Cu(1,3-benzendicarboxylate). The μSR is carried to temperatures as low as 45 mK. The spin-Hamiltonian parameters are determined from the analysis of the magnetization and ESR data. We find that this compound has anisotropic ferromagnetic interactions. Nevertheless, no spin freezing is observed even at temperatures two orders of magnitude lower than the coupling constants. In light of this finding, the relation between persistent spin dynamics and spin liquids on kagome lattices is reexamined.
