LaRuO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Ru(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles range from 32-33°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent La(1) and two equivalent Ru(1) atoms to form distorted OLa2Ru2 tetrahedra that share corners with eight equivalent O(2)La3Ru2 square pyramids, corners with four equivalent O(1)La2Ru2 tetrahedra, and edges with six equivalent O(2)La3Ru2 square pyramids. In the second O site, O(2) is bonded to three equivalent La(1) and two equivalent Ru(1) atoms to form distorted OLa3Ru2 square pyramids that share corners with nine equivalent O(2)La3Ru2 square pyramids, corners with four equivalent O(1)La2Ru2 tetrahedra, edges with six equivalent O(2)La3Ru2 square pyramids, and edges with three equivalent O(1)La2Ru2 tetrahedra.
LaRuO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There is one shorter (2.38 Å) and one longer (2.46 Å) La(1)-O(1) bond length. There are a spread of La(1)-O(2) bond distances ranging from 2.42-2.77 Å. Ru(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles range from 32-33°. Both Ru(1)-O(1) bond lengths are 2.06 Å. All Ru(1)-O(2) bond lengths are 2.10 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent La(1) and two equivalent Ru(1) atoms to form distorted OLa2Ru2 tetrahedra that share corners with eight equivalent O(2)La3Ru2 square pyramids, corners with four equivalent O(1)La2Ru2 tetrahedra, and edges with six equivalent O(2)La3Ru2 square pyramids. In the second O site, O(2) is bonded to three equivalent La(1) and two equivalent Ru(1) atoms to form distorted OLa3Ru2 square pyramids that share corners with nine equivalent O(2)La3Ru2 square pyramids, corners with four equivalent O(1)La2Ru2 tetrahedra, edges with six equivalent O(2)La3Ru2 square pyramids, and edges with three equivalent O(1)La2Ru2 tetrahedra.
