The structure described by KZnP(CO3)2 crystallizes in the orthorhombic Pna2_1 space group. K(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form ZnO4 tetrahedra that share corners with three equivalent P(1)CO3 tetrahedra. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to one C(2), one P(1), and one O(4) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(1), one O(5), and one O(6) atom. P(1) is bonded to one C(1), one O(1), one O(2), and one O(3) atom to form distorted PCO3 tetrahedra that share corners with three equivalent Zn(1)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one K(1) and one C(1) atom. In the second O site, O(5) is bonded in a 3-coordinate geometry to one K(1), one Zn(1), and one C(2) atom. In the third O site, O(6) is bonded in a distorted single-bond geometry to one K(1) and one C(2) atom. In the fourth O site, O(1) is bonded in a distorted bent 120 degrees geometry to one K(1), one Zn(1), and one P(1) atom. In the fifth O site, O(2) is bonded in a 2-coordinate geometry to one K(1), one Zn(1), and one P(1) atom. In the sixth O site, O(3) is bonded in a 2-coordinate geometry to one K(1), one Zn(1), and one P(1) atom. is represented by the CIF file [CIF]
