PbHAsO4 crystallizes in the monoclinic P2/c space group. Pb(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. As(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one As(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one As(1) atom.
PbHAsO4 crystallizes in the monoclinic P2/c space group. Pb(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. There are two shorter (2.42 Å) and two longer (2.53 Å) Pb(1)-O(2) bond lengths. As(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. Both As(1)-O(1) bond lengths are 1.74 Å. Both As(1)-O(2) bond lengths are 1.72 Å. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both H(1)-O(1) bond lengths are 1.21 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one As(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one As(1) atom.
