Materials Data on As2Ru by Materials Project
RuAs2 is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Ru6+ is bonded to six equivalent As3- atoms to form RuAs6 octahedra that share corners with eight equivalent RuAs6 octahedra, corners with six equivalent AsAsRu3 tetrahedra, and edges with two equivalent RuAs6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are two shorter (2.47 Å) and four longer (2.50 Å) Ru–As bond lengths. As3- is bonded to three equivalent Ru6+ and one As3- atom to form distorted AsAsRu3 tetrahedra that share corners with three equivalent RuAs6 octahedra, corners with thirteen equivalent AsAsRu3 tetrahedra, and an edgeedge with one AsAsRu3 tetrahedra. The corner-sharing octahedra tilt angles range from 70–72°. The As–As bond length is 2.52 Å.
