Materials Data on K2RbNa by Materials Project
RbK2Na crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two RbK2Na ribbons oriented in the (0, 1, 0) direction. Rb is bonded in a linear geometry to two equivalent K atoms. Both Rb–K bond lengths are 4.70 Å. K is bonded in a linear geometry to one Rb and one Na atom. The K–Na bond length is 3.77 Å. Na is bonded in a linear geometry to two equivalent K atoms.
