The structure described by HgSiP2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Hg(1) is bonded to four equivalent P(1) atoms to form HgP4 tetrahedra that share corners with four equivalent Hg(1)P4 tetrahedra and corners with eight equivalent Si(1)P4 tetrahedra. Si(1) is bonded to four equivalent P(1) atoms to form SiP4 tetrahedra that share corners with four equivalent Si(1)P4 tetrahedra and corners with eight equivalent Hg(1)P4 tetrahedra. P(1) is bonded to two equivalent Hg(1) and two equivalent Si(1) atoms to form corner-sharing PSi2Hg2 tetrahedra. is represented by the CIF card [CIF]
