The material structure described by K2Mo2O15 crystallizes in the triclinic P-1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to one O(10), one O(11), one O(15), one O(6), one O(7), and one O(9) atom to form distorted KO6 octahedra that share corners with two equivalent Mo(2)O5 trigonal bipyramids. In the second K site, K(2) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(5), one O(7), one O(8), and two equivalent O(14) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 5-coordinate geometry to one O(1), one O(13), one O(15), one O(6), and one O(8) atom. In the second Mo site, Mo(2) is bonded to one O(1), one O(10), one O(11), one O(12), and one O(3) atom to form distorted MoO5 trigonal bipyramids that share corners with two equivalent K(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-53°. There are fifteen inequivalent O sites.
