### Abstract

We combine the finite-size scaling method with a multistage real-space renormalization-group procedure to examine the Mott metal-insulator transition (MIT) on a nonpartite lattice. Based on the Hubbard model, we have found that there exists a critical point U/t=12.5 for the MIT with the correlation length exponent v = 1. At the critical point, the charge gap scales with the system size as Δ_{g}∼1/L^{0.91}.
