The compound described by (Pb(BO2)2)12O2 crystallizes in the trigonal R-3m space group. The structure consists of three water atoms inside a Pb(BO2)2 framework. In the Pb(BO2)2 framework, there are two inequivalent B sites. In the first B site, B(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing BO4 tetrahedra. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(3) and two equivalent O(1) atoms. Pb(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent B(1) and one Pb(1) atom. In the second O site, O(3) is bonded in a 3-coordinate geometry to one B(2) and two equivalent Pb(1) atoms. In the third O site, O(1) is bonded in a bent 120 degrees geometry to one B(1) and one B(2) atom. is represented by the CIF card [CIF]
