Ba2MgGdCu3O7 crystallizes in the orthorhombic Pmm2 space group. Ba(1) is bonded in a 9-coordinate geometry to one Mg(1), two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Mg(1) is bonded in a bent 150 degrees geometry to two equivalent Ba(1) and two equivalent O(4) atoms. Gd(1) is bonded in a body-centered cubic geometry to four equivalent O(2) and four equivalent O(3) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second Cu site, Cu(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to four equivalent Ba(1) and one Cu(2) atom. In the second O site, O(2) is bonded to two equivalent Ba(1), two equivalent Gd(1), and two equivalent Cu(1) atoms to form a mixture of corner and edge-sharing OBa2Gd2Cu2 octahedra. The corner-sharing octahedral tilt angles range from 1-2°. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Gd(1), and two equivalent Cu(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Cu(2) atoms.
