The compound described by ErCPH3O6H2O crystallizes in the triclinic P-1 space group. The structure consists of two water molecules inside a ErCPH3O6 framework. In the ErCPH3O6 framework, Er(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(5), one O(6), two equivalent O(3), and two equivalent O(7) atoms. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(6) atom. P(1) is bonded in a distorted tetrahedral geometry to one H(4), one O(3), one O(5), and one O(7) atom. There are three inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one O(2) atom. In the second H site, H(4) is bonded in a single-bond geometry to one P(1) atom. In the third H site, H(5) is bonded in a single-bond geometry to one O(2) and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Er(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to one Er(1), one H(2), and one H(5) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Er(1) and one P(1) atom. In the fourth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Er(1) and one P(1) atom. In the fifth O site, O(6) is bonded in a distorted trigonal planar geometry to one Er(1), one C(1), and one H(5) atom. In the sixth O site, O(7) is bonded in a 3-coordinate geometry to two equivalent Er(1) and one P(1) atom. is represented by the CIF card [CIF]
