High-pressure structures of germane (GeH₄) are explored through ab initio evolutionary methodology to reveal a metallic monoclinic structure of C2/c (4 molecules/cell). The C2/c structure consists of layerlike motifs containing novel ``H₂'' units. Enthalpy calculations suggest a remarkably wide decomposition (Ge+H₂) pressure range of 0--196 GPa, above which C2/c structure is stable. Perturbative linear-response calculations for C2/c GeH₄ at 220 GPa predict a large electron-phonon coupling parameter of 1. 12 and the resulting superconducting critical temperature reaches 64 K.
