A unique chemisorption structure has been determined for the ({radical}(3){times}{radical}(3))R30{degree}thinspH-Be(0001) phase formed at a saturation coverage of 1 ML and T{le}270K. The analysis of low-energy electron diffraction data shows that (1) /(3) of the Be top layer atoms are removed to form a honeycomb structure of Be vacancies. Each vacancy is decorated by three H adatoms bonded in tilted bridge sites with a H-Be bond length and angle of 1.53 {Angstrom} ({plus_minus}0.2) and 42{degree}({plus_minus}10), respectively. {copyright} {ital 1999} {ital The American Physical Society}
