PbAsO4 crystallizes in the monoclinic P2/c space group. Pb(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. As(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one As(1) atom. In the second O site, O(1) is bonded in a single-bond geometry to two equivalent Pb(1) and one As(1) atom.
PbAsO4 crystallizes in the monoclinic P2/c space group. Pb(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two shorter (2.83 Å) and two longer (2.85 Å) Pb(1)-O(1) bond lengths. There are two shorter (2.51 Å) and two longer (2.58 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 1.75 Å. Both As(1)-O(2) bond lengths are 1.71 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one As(1) atom. In the second O site, O(1) is bonded in a single-bond geometry to two equivalent Pb(1) and one As(1) atom.
