We have studied the effect of pressure on the electrical resistivity of the antiferromagnet CeMg2Cu9 which crystallizes in the hexagonal structure. The structure is built up of alternating MgCu2 Laves-type and CeCu5-type layers along the [0001] direction. The Néel temperature TN = 2.7 K at ambient pressure decreases with increasing pressure p and disappears at a critical pressure pc ≃ 2.5 GPa. Correspondingly, the residual resistivity ρ0 and the coefficient A in a Fermi-liquid relation ρ = ρ0 + AT2 are found to have maximum values around pc.
