Magnetic property of antiferromagnets with two-dimensional distorted triangular lattice structures, $\beta^{\prime}$-Me 4P[ Pd(dmit) 2] 2 and $\beta^{\prime}$-Et 2Me 2P[ Pd(dmit) 2] 2, was investigated by the muon spin relaxation method. Enhancement of the muon spin depolarization associated with the critical slow-down effect suggests that the spin dynamics due to the two- and three-dimensional magnetic correlations reflects the deviation from the triangular lattice. Key words. Pd(dmit) 2 - muon spin relaxation - magnetic transition.
