The material structure described by V6Cu2O15 crystallizes in the triclinic P-1 space group. There are three inequivalent V sites. In the first V site, V(1) is bonded in a 6-coordinate geometry to one O(1), one O(6), one O(7), and three equivalent O(4) atoms. In the second V site, V(2) is bonded in a 6-coordinate geometry to one O(2), one O(4), one O(5), one O(6), and two equivalent O(7) atoms. In the third V site, V(3) is bonded in a 5-coordinate geometry to one O(3), one O(6), and three equivalent O(8) atoms. Cu(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(3), and two equivalent O(5) atoms. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one V(1) and one Cu(1) atom. In the second O site, O(2) is bonded in a linear geometry to two equivalent V(2) atoms. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one V(3) and two equivalent Cu(1) atoms. In the fourth O site, O(4) is bonded to one V(2) and three equivalent V(1) atoms to form a mixture of distorted edge and corner-sharing OV4 trigonal pyramids. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one V(2) and two equivalent Cu(1) atoms. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one V(1), one V(2), and one V(3) atom. In the seventh O site, O(7) is bonded in a distorted T-shaped geometry to one V(1) and two equivalent V(2) atoms. In the eighth O site, O(8) is bonded in a distorted trigonal non-coplanar geometry to three equivalent V(3) atoms. is represented by the CIF file [CIF]
