CuCO3 crystallizes in the monoclinic Cm space group. Cu(1) is bonded to one O(2) and four equivalent O(1) atoms to form edge-sharing CuO5 square pyramids. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cu(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Cu(1) and one C(1) atom.
CuCO3 crystallizes in the monoclinic Cm space group. Cu(1) is bonded to one O(2) and four equivalent O(1) atoms to form edge-sharing CuO5 square pyramids. The Cu(1)-O(2) bond length is 2.22 Å. There are two shorter (1.98 Å) and two longer (2.05 Å) Cu(1)-O(1) bond lengths. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. The C(1)-O(2) bond length is 1.24 Å. Both C(1)-O(1) bond lengths are 1.33 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cu(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Cu(1) and one C(1) atom.
