CuBO2 crystallizes in the trigonal R-3m space group. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. B(1) is bonded to six equivalent O(1) atoms to form edge-sharing BO6 octahedra. O(1) is bonded to one Cu(1) and three equivalent B(1) atoms to form a mixture of distorted edge and corner-sharing OCuB3 trigonal pyramids.
CuBO2 crystallizes in the trigonal R-3m space group. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Cu(1)-O(1) bond lengths are 1.91 Å. B(1) is bonded to six equivalent O(1) atoms to form edge-sharing BO6 octahedra. All B(1)-O(1) bond lengths are 1.70 Å. O(1) is bonded to one Cu(1) and three equivalent B(1) atoms to form a mixture of distorted edge and corner-sharing OCuB3 trigonal pyramids.
