The elastic properties of Mg 2.12(2) Fe 0.21(2) Ni 0.01 Si 1.15(1) O 6 H 2.67(8)  phase E single crystals with Fe 3+ /ΣFe = 0.25(3) have been determined by Brillouin spectroscopy at ambient conditions. We find that that the elasticity of iron-bearing phase E is described by the six independent stiffness tensor components (all in units of GPa):  C  11  = 192.2(6),  C  12  = 56.4(8),  C  13  = 43.5(8),  C  14  = –4.3(3),  C  33  = 192.1(7),  C  44  = 46.4(3). The Voigt-Reuss-Hill averages of bulk and shear moduli are 95.9(4) and 59.6(2) GPa, respectively. The aggregate velocities of iron-bearing phase E are  v  P  = 7.60(2) and  v  S  = 4.43(1) km/s, markedly lower than those of major mantle minerals at ambient conditions. Modeling based on our results suggests that the presence of iron-bearing phase E may reduce the sound wave velocities in upper mantle and transition zone rocks, making it a possible target for future seismological investigations aiming to map hydration in subducting slabs.
