The crystal structure described by HgIn3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded to twelve equivalent In(1) atoms to form HgIn12 cuboctahedra that share corners with six equivalent Hg(1)In12 cuboctahedra, corners with twelve equivalent In(1)In8Hg4 cuboctahedra, edges with eighteen equivalent In(1)In8Hg4 cuboctahedra, faces with eight equivalent Hg(1)In12 cuboctahedra, and faces with twelve equivalent In(1)In8Hg4 cuboctahedra. In(1) is bonded to four equivalent Hg(1) and eight equivalent In(1) atoms to form InIn8Hg4 cuboctahedra that share corners with four equivalent Hg(1)In12 cuboctahedra, corners with fourteen equivalent In(1)In8Hg4 cuboctahedra, edges with six equivalent Hg(1)In12 cuboctahedra, edges with twelve equivalent In(1)In8Hg4 cuboctahedra, faces with four equivalent Hg(1)In12 cuboctahedra, and faces with sixteen equivalent In(1)In8Hg4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
