BaBiO2I is lead oxide-derived structured and crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and four equivalent I(1) atoms. Bi(1) is bonded to four equivalent O(1) atoms to form distorted edge-sharing BiO4 trigonal pyramids. O(1) is bonded to two equivalent Ba(1) and two equivalent Bi(1) atoms to form OBa2Bi2 tetrahedra that share corners with four equivalent O(1)Ba2Bi2 tetrahedra, corners with eight equivalent I(1)Ba4 tetrahedra, and edges with four equivalent O(1)Ba2Bi2 tetrahedra. I(1) is bonded to four equivalent Ba(1) atoms to form IBa4 tetrahedra that share corners with four equivalent I(1)Ba4 tetrahedra, corners with sixteen equivalent O(1)Ba2Bi2 tetrahedra, and edges with four equivalent I(1)Ba4 tetrahedra.
BaBiO2I is lead oxide-derived structured and crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and four equivalent I(1) atoms. All Ba(1)-O(1) bond lengths are 2.70 Å. There are two shorter (3.65 Å) and two longer (3.78 Å) Ba(1)-I(1) bond lengths. Bi(1) is bonded to four equivalent O(1) atoms to form distorted edge-sharing BiO4 trigonal pyramids. All Bi(1)-O(1) bond lengths are 2.25 Å. O(1) is bonded to two equivalent Ba(1) and two equivalent Bi(1) atoms to form OBa2Bi2 tetrahedra that share corners with four equivalent O(1)Ba2Bi2 tetrahedra, corners with eight equivalent I(1)Ba4 tetrahedra, and edges with four equivalent O(1)Ba2Bi2 tetrahedra. I(1) is bonded to four equivalent Ba(1) atoms to form IBa4 tetrahedra that share corners with four equivalent I(1)Ba4 tetrahedra, corners with sixteen equivalent O(1)Ba2Bi2 tetrahedra, and edges with four equivalent I(1)Ba4 tetrahedra.
