Materials Data on CaHg2Pb by Materials Project
CaHg2Pb crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two CaHg2Pb ribbons oriented in the (1, 0, 0) direction. Ca is bonded in a linear geometry to two equivalent Hg atoms. Both Ca–Hg bond lengths are 3.09 Å. Hg is bonded in a linear geometry to one Ca and one Pb atom. The Hg–Pb bond length is 2.94 Å. Pb is bonded in a linear geometry to two equivalent Hg atoms.
