The compound described by KLa(PO3)4 crystallizes in the orthorhombic Cmc2_1 space group. K(1) is bonded in a 6-coordinate geometry to one O(6), one O(7), two equivalent O(1), and two equivalent O(5) atoms. La(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms to form distorted LaO6 pentagonal pyramids that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(4), one O(5), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one La(1)O6 pentagonal pyramid,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. In the second P site, P(2) is bonded to one O(1), one O(3), one O(4), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent La(1)O6 pentagonal pyramids,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. There are seven inequivalent O sites. In the first O site, O(6) is bonded in a distorted bent 150 degrees geometry to one K(1) and two equivalent P(1) atoms. In the second O site, O(7) is bonded in a distorted bent 120 degrees geometry to one K(1) and two equivalent P(2) atoms. In the third O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one La(1), and one P(2) atom. In the fourth O site, O(2) is bonded in a single-bond geometry to one P(1) atom. In the fifth O site, O(3) is bonded in a distorted linear geometry to one La(1) and one P(2) atom. In the sixth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one P(1) and one P(2) atom. In the seventh O site, O(5) is bonded in a 2-coordinate geometry to one K(1), one La(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
