Materials Data on KRbNa2 by Materials Project
RbKNa2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two RbKNa2 ribbons oriented in the (0, 1, 0) direction. Rb is bonded in a linear geometry to two equivalent Na atoms. Both Rb–Na bond lengths are 3.92 Å. K is bonded in a linear geometry to two equivalent Na atoms. Both K–Na bond lengths are 3.88 Å. Na is bonded in a linear geometry to one Rb and one K atom.
