The compound described by K4P6O19CoO6 crystallizes in the orthorhombic Fmm2 space group. The structure consists of four cobalt;hexahydrate molecules inside a K4P6O19 framework. In the K4P6O19 framework, there are two inequivalent K sites. In the first K site, K(1) is bonded to one O(5), one O(8), two equivalent O(1), and two equivalent O(3) atoms to form KO6 octahedra that share  a cornercorner with one K(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and corners with four equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(5), two equivalent O(7), and two equivalent O(9) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(5), one O(9), and two equivalent O(7) atoms to form PO4 tetrahedra that share  a cornercorner with one K(1)O6 octahedra and corners with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 38°. In the second P site, P(2) is bonded to one O(1), one O(3), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent K(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 46-62°. There are seven inequivalent O sites. In the first O site, O(8) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1) atoms. In the second O site, O(9) is bonded in a distorted single-bond geometry to two equivalent K(2) and one P(1) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one P(2) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to one K(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one P(1) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to two equivalent P(2) atoms. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one K(2), one P(1), and one P(2) atom. is represented by the CIF card [CIF]
