The compound described by MnHg2Te3 is Lavarevi\'{c}ite-like structured and crystallizes in the trigonal P3m1 space group. Mn(1) is bonded to one Te(3) and three equivalent Te(2) atoms to form MnTe4 tetrahedra that share corners with three equivalent Hg(1)Te4 tetrahedra, corners with three equivalent Hg(2)Te4 tetrahedra, and corners with six equivalent Mn(1)Te4 tetrahedra. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded to one Te(1) and three equivalent Te(3) atoms to form HgTe4 tetrahedra that share corners with three equivalent Mn(1)Te4 tetrahedra, corners with three equivalent Hg(2)Te4 tetrahedra, and corners with six equivalent Hg(1)Te4 tetrahedra. In the second Hg site, Hg(2) is bonded to one Te(2) and three equivalent Te(1) atoms to form HgTe4 tetrahedra that share corners with three equivalent Mn(1)Te4 tetrahedra, corners with three equivalent Hg(1)Te4 tetrahedra, and corners with six equivalent Hg(2)Te4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to one Hg(1) and three equivalent Hg(2) atoms to form TeHg4 tetrahedra that share corners with three equivalent Te(2)Mn3Hg tetrahedra, corners with three equivalent Te(3)MnHg3 tetrahedra, and corners with six equivalent Te(1)Hg4 tetrahedra. In the second Te site, Te(2) is bonded to three equivalent Mn(1) and one Hg(2) atom to form TeMn3Hg tetrahedra that share corners with three equivalent Te(1)Hg4 tetrahedra, corners with three equivalent Te(3)MnHg3 tetrahedra, and corners with six equivalent Te(2)Mn3Hg tetrahedra. In the third Te site, Te(3) is bonded to one Mn(1) and three equivalent Hg(1) atoms to form TeMnHg3 tetrahedra that share corners with three equivalent Te(1)Hg4 tetrahedra, corners with three equivalent Te(2)Mn3Hg tetrahedra, and corners with six equivalent Te(3)MnHg3 tetrahedra. is represented by the CIF file [CIF]
