YSi2 is hexagonal omega structure-like structured and crystallizes in the monoclinic C2/c space group. Y(1) is bonded to twelve equivalent Si(1) atoms to form a mixture of edge and face-sharing YSi12 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to six equivalent Y(1) and three equivalent Si(1) atoms.
