The crystal structure described by Li3CoCPO7 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(4), and one O(5) atom. In the second Li site, Li(2) is bonded to one O(2), one O(3), one O(5), one O(6), and one O(7) atom to form distorted LiO5 trigonal bipyramids that share corners with three equivalent P(1)O4 tetrahedra and edges with two equivalent Co(1)O5 trigonal bipyramids. In the third Li site, Li(3) is bonded in a 6-coordinate geometry to one O(1), one O(3), one O(4), one O(5), one O(6), and one O(7) atom. Co(1) is bonded to one O(2), one O(3), one O(4), one O(6), and one O(7) atom to form distorted CoO5 trigonal bipyramids that share corners with three equivalent P(1)O4 tetrahedra and edges with two equivalent Li(2)O5 trigonal bipyramids. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. P(1) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent Li(2)O5 trigonal bipyramids and corners with three equivalent Co(1)O5 trigonal bipyramids. There are seven inequivalent O sites. In the first O site, O(6) is bonded to one Li(2), one Li(3), one Co(1), and one P(1) atom to form distorted OLi2CoP trigonal pyramids that share corners with two equivalent O(2)Li2CoC tetrahedra, corners with four equivalent O(7)Li2CoP tetrahedra,  a cornercorner with one O(4)Li2CoP trigonal pyramid, and  an edgeedge with one O(4)Li2CoP trigonal pyramid. In the second O site, O(7) is bonded to one Li(2), one Li(3), one Co(1), and one P(1) atom to form OLi2CoP tetrahedra that share corners with three equivalent O(4)Li2CoP trigonal pyramids, corners with four equivalent O(6)Li2CoP trigonal pyramids, and  an edgeedge with one O(2)Li2CoC tetrahedra. In the third O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Li(1), one Li(3), and one C(1) atom. In the fourth O site, O(2) is bonded to one Li(1), one Li(2), one Co(1), and one C(1) atom to form a mixture of distorted corner and edge-sharing OLi2CoC tetrahedra. In the fifth O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Li(2), one Li(3), one Co(1), and one C(1) atom.
