We report zero-field (ZF) μSR on a series of antiferromagnetic (AFM) samples of YBa2Cu3O6.4 reacted with water. We find several oscillating signals whose amplitudes vary with water content and temperature, and for high water contents, a non-oscillating component. The Néel transition is 395(5) K, characteristic of the undoped CuO2 bilayer. Initial comparison with ZFμSR and ŻFNMR\} measurements in related AFMs (PrBa2Cu3O7 and H doped YBa2Cu3O7) suggests a similar muon site and an \{AF\} structure which is similar, but distinct from YBa2Cu3O6.
