[en] In this work we report the effects of hydrostatic pressure and magnetic field on the electronic transport properties of the antiferromagnetic compound Eu_3Ir_4Sn_1_3 (T_N ∼ 10 K). Single crystals of Eu_3Ir_4Sn_1_3 were synthesized using the Sn self-flux technique. DC electrical resistivity measurements as a function of temperature were performed by means of the four- probe technique. The high-temperature anomaly at T* ∼ 57 K attributed to a structural distortion of the Sn1Sn2_1_2 cages in Eu_3Ir_4Sn_1_3 is rapidly decreased to lower temperatures at a rate dT*/dP = 2 K/kbar, while the antiferromagnetic transition due to the Eu"2"+ ions is only weakly affected. Our data do not indicate any magnetoelastic effect associated with the structural instability at T* . Furthermore, the suppression of the lattice distortion by application of external pressure is not accompanied by the emergence of superconductivity, possibly due to strong magnetic correlations between the Eu"2"+ localized magnetic moments
