Triply excited autodissociating resonant states of positronium hydride are investigated by using a method of complex-coordinate rotation. States with which the positron is attaching to the doubly excited 2{ital s}{sup 2} {sup 1}S{sup e} state of the H{sup {minus}} ion are calculated. Resonance parameters (both positions and widths) are obtained by employing elaborated Hylleraas-type wave functions in which all six interparticle coordinates are included.
