Materials Data on K2RbAs by Materials Project
RbK2As is Cyanogen Chloride-like structured and crystallizes in the orthorhombic Immm space group. The structure is zero-dimensional and consists of two rubidium molecules and two K2As clusters. In each K2As cluster, K1+ is bonded in a single-bond geometry to one As3- atom. The K–As bond length is 3.16 Å. As3- is bonded in a linear geometry to two equivalent K1+ atoms.
