BiAsO2 crystallizes in the tetragonal I4_1/amd space group. Bi(1) is bonded to six equivalent O(1) atoms to form edge-sharing BiO6 octahedra. As(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Bi(1) and two equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing OBi3As2 trigonal bipyramids.
BiAsO2 crystallizes in the tetragonal I4_1/amd space group. Bi(1) is bonded to six equivalent O(1) atoms to form edge-sharing BiO6 octahedra. There are two shorter (2.45 Å) and four longer (2.51 Å) Bi(1)-O(1) bond lengths. As(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All As(1)-O(1) bond lengths are 2.30 Å. O(1) is bonded to three equivalent Bi(1) and two equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing OBi3As2 trigonal bipyramids.
