Materials Data on NaCaHg2 by Materials Project
NaCaHg2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two NaCaHg2 ribbons oriented in the (0, 1, 0) direction. Na is bonded in a linear geometry to two equivalent Hg atoms. Both Na–Hg bond lengths are 3.10 Å. Ca is bonded in a linear geometry to two equivalent Hg atoms. Both Ca–Hg bond lengths are 3.39 Å. Hg is bonded in a linear geometry to one Na and one Ca atom.
