The structure described by MgCoBiO3 crystallizes in the tetragonal P4mm space group. Mg(1) is bonded in a 4-coordinate geometry to one Bi(1) and four equivalent O(1) atoms. Co(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. Bi(1) is bonded to one Mg(1) and four equivalent O(2) atoms to form distorted BiMgO4 square pyramids that share corners with four equivalent Bi(1)MgO4 square pyramids, corners with four equivalent O(1)Mg2Co2 trigonal pyramids, and edges with four equivalent Bi(1)MgO4 square pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent Co(1) atoms to form distorted OMg2Co2 trigonal pyramids that share corners with two equivalent Bi(1)MgO4 square pyramids, corners with two equivalent O(2)CoBi4 square pyramids, corners with four equivalent O(1)Mg2Co2 trigonal pyramids, and edges with four equivalent O(1)Mg2Co2 trigonal pyramids. In the second O site, O(2) is bonded to one Co(1) and four equivalent Bi(1) atoms to form distorted OCoBi4 square pyramids that share corners with four equivalent O(2)CoBi4 square pyramids, corners with four equivalent O(1)Mg2Co2 trigonal pyramids, and edges with four equivalent O(2)CoBi4 square pyramids. is represented by the CIF file [CIF]
